PREFACE
T his book is written primarily for anyonewho is learning anatomy for thefollowingreasons:
•Toanalyzemovements,activitiesandexercises.•Tounderstandthemusclesthatareinvolvedinathleticinjuries.•Toprescribeexercisesforparticularmusclegroups.• To develop an exercise program designed to develop and strength theskeletalmuscles.
•Todetermine themuscles that are involved inpathological conditionsororthopedicproblems.
Most of the individuals who have the above reasons for learningmusculoskeletal anatomy are likely to be in the fields of exercise physiology,personal training, athletic training, physical education, physical therapy,coaching, or nursing. Students in these disciplines, during their academiccurricula, takeanatomyandphysiology frombiologydepartmentswhousuallyservicethesefields.Thetypicalanatomyclassatmostuniversitiesincludestheanatomyofallofthebody’ssystems:theskeletalsystem(osteology);thesystemof joints and articulations (arthrology); the muscular system (myology); thevascular system (angiology), which includes the circulatory system and thelymphatic system; the nervous system (neurology),which includes the centralnervous system (CNS) and the peripheral nervous system (PNS); theintegumentarysystem;thealimentarysystem(oftencalledthedigestivesystem);the urogenital system; and the endocrine system. In exercise studies, thecardiorespiratorysystemisoftenreferredtoasindicatingthetwosystemsmost
involvedinaerobicexercise:theangiologyandrespiratorysystems.Becausethetypicalanatomyclassonlylastsfor12-14weeks,lessthanoneweekisnormallyspentoneachsystem.Evenatwo-semesterclasswouldonlydoublethisamountoftime.Asaresult, individualsinthesefieldswhoareinterestedinbonesandthemuscles that attach to themhave limited timespenton themost importantsystemforthem:namelythemusculoskeletalsystems.
As a consequence, most disciplines usually teach an additionalmusculoskeletalanatomycoursefortheirstudents,whichteachesstudentsaboutmuscles,howmusclescreatemovement,howtheyareusedinmovement,howthey are developed, and how they are rehabilitated after injury. It is forindividualsinterestedinthistypeofinformationthatthisbookiswritten.
Relatively few textbooks are devoted exclusively to musculoskeletalanatomy. Students and instructors alike buy attractive muscle charts, whichdisplayallthesurfacemuscles,andwhichareusuallylabeled,butarelimitedinscope. For example, if you are interested in muscle anatomy for theaforementioned practical reasons, then you must know where the musclesoriginateandwheretheyinsertsothattheiractioncanbedetermined.Examinethe muscle charts so often purchased by those who want to know where themuscles are and what they look like. These charts do not show the muscle’soriginsorinsertionsbecausetheycannotbeseenordetermined;onlythebellyofthemuscleisshown.
This point can be illustrated by a simple example, looking at a commonsuperficialmusclelikethebiceps.Mostmusclechartsclearlyshowthebiceps–it’s an upper, anterior, superficial armmuscle.Nowask yourself the question:where is its origin? The origin is on two places on the scapula (the coracoidprocessandthesupraglenoidtubercleoftheglenoidfossa).Thesecan’tbeseenbecausethebicepsisfoldedunderthedeltoidandthepectoralismajor.Whereisits insertion? The insertion is the radial tuberosity. That too cannot be seenbecause it is under the muscles and tendons of the forearm. In reality, theanatomy chart only shows that the bicep is an anterior, superficial, upper armmuscle,butitdoesnotshowwherethemusclecomesfrom,orwhereitgoes.
One of the primary purposes of this book is to address that issue bypresentingdrawingsofall the skeletal, locomotormuscles, so thatataglance,
youwill be able to clearly see the origin of themuscle,where it inserts, andhencebeabletodetermineitsaction.Iftheoriginandtheinsertionofamuscleareknown,noneedexiststolearnitsactionbecauseitsactioncanbedeterminedbyknowingwhereitattaches,andwhathappenswhenitshortens.
Theotherphenomenon is thatpractitionerswhousemusclenames in theirjob enjoy impressing clients with their knowledge of the technical names ofmuscles. The human body has 680 muscles, and that’s a lot of names tomemorize. If you know the name of jointmovements (which can typically belearnedinabout20minutes),theninlessthanahalf-hour,youwillalsohaveareasonable opportunity to learn the names of all the muscles, and in a moremeaningfulmanner.Again,anillustrationcanhelpclarifythispoint.
Ayoungexercise leaderata localhealth facilitywasexplaining tome thearmcurlontheNautilusmachine.Hesaidthatthiswasanexcellentexerciseforthebiceps.Soitis!But,hiscommentwasalsoverydiscriminatory.Whataboutthebrachialis,thepronatorteres,thesupinator,thebrachioradialis,andtheflexordigitorumsublimus?Thesemusclesarealsousedinthebicepscurl.Whynamethebiceps?Anumberofpossiblereasonsexist.First,heprobablydidn’tknowthose other muscle’s names, so he was showing off his limited knowledge.Second,whocares?Third,hewantedtosoundeducated.
Interestingly,thebrachialis,whichliesunderthebicepsandcan’tbeseenonamusclechart,isatruerflexoroftheelbowthanthebiceps,sincethebicepshastwootheractionsinvolvingtheshoulderandradial-ulnajoint,andthebrachialisonly has one action – elbow flexion. If this young man knew the jointmovements,thennamingallthemusclesinvolvedinthecurlissimple.Bendingthe elbow involves a joint action called elbow flexion.Accordingly,when theyoungmanwas explaining themuscles involved in the curl, he simply couldhavesaidthatperformingthecurlexercisestheelbowflexors(ofwhichtherearesixmuscles).Thiswayhewouldhavementionedall themuscles involvedanddidn’thavetoworryaboutrememberingallthemuscle’snames.
Likewise,whenexplainingthemusclesinvolvedinthelegpress(ofwhich,therearemanymore than thearmcurl) it couldbeexplained that themusclesused are the knee extensors and the hip extensors. This book is designed toteach, illustrate, and explain all of the body’s joint movements. Master these
movements,andyou’vemasteredalltheskeletalmuscleactionsinthebody.Inaddition, the muscles in each of the major groups of the body will beindividuallyillustratedandshown.
Anotherdesirablefeatureofthisbookisthatitcouldbeusedasacoloringbook of skeletal muscles. One of the best ways of learning the origin andinsertionofmusclesistodrawthemontheskeletonontheindividualbones.Forthisreason,thebookincludesseveralblankdrawingssothateachmusclecanbedrawnandcanbeseeninitsentirety,notconfusedwithoroverlappingwithanyothermuscles.Color-coding theorigin and insertion further helps the learningprocess.
Understanding the joints actions also facilitates the learning of themuscleactions. In order for a muscle to work a joint, it must cross the joint. Thequestioncanbeaskedifthebrachialiscrossestheelbowjoint,whatisitsactionon the elbow joint? The elbow joint has only two actions: it either flexes orextends. Since it crosses the anterior of the joint, it can only flex the elbow.Sincetherearenootheractions,therecanbenootheractiontoconsider(unlessitcrossesanotherjoint).
Anotherexamplewillhelpclarifythisfactor.(Keepinmindthatatthisstageinthebook,don’tconcernyourselfwithrememberingtheseexamples–theywillbedealtwith indetail as thebookprogresses.Right now, they areonlybeingusedtoillustrateaparticularpoint.)Takethemiddledeltoid,forexample,whichcrosses the shoulder joint.The shoulder jointhas sixpossible actions: flexion,extension, abduction, adduction, inward rotation, and outward rotation.Therefore, themiddle deltoidmust have one or some of these actions, but noothers.Sincethemiddledeltoidcomesrightoverthetopoftheshoulder(fromthe acromion process of the scapula to the lateralmiddle humerus), it has noangle on the arm, therefore cannot flex or extend the arm.To flex the arm, itwouldhavetobeinfrontofthearminordertopullitupintoflexion.Toextendthearm,itwouldhavetobebehindthearm,soitcouldpullthearmbackintoextension. By the same reasoning, with no angle on the humerus, it neitherinternally nor externally rotates the arm. Therefore, the middle deltoid onlyabductsthearm(comesoverthetopoftheshoulderandpullsthelateralsurfaceof thehumerus intoabduction).Thisapproachoffersaveryeasyway to learnmuscleactions.
Bones have bonymarkings, which are named and illustrated. These bonymarkingsaretheoriginsandinsertionslocationsofmuscles.Asaresult,byfirstlearning all the bony markings, the body’s muscle origins and insertions arelearnedbeforethestudyofmusclesisevenstarted.

FITNESSPROFESSIONALS’GUIDETOMUSCULOSKELETALANATOMYANDHUMANMOVEMENT–TERMINOLOGY
CHAPTER1•TERMINOLOGY
Most anatomy books have an extensive glossary of terms covering all thesystemsofthebody.Sincethisbookisprimarilydirectedtothemusculoskeletalsystem, this terminology section deals only with terms related to bones andmuscles.
AnatomicalPosition
Thisisthestartingpositionforallmuscleactions.RefertoFigure1-1.Thebodyisstandinguprightwiththearmsat thesidesandthepalmsof thehandfacingforward (supinated). All muscle actions are given from this position, andalthoughmuscleactionscanbedonefromotherpositions,thetextbookactionisfromthestartingposition.Forexample:standingintheanatomicalposition,flexthe elbows.The forearmcomes forward in the sagittal plane.However, if youstand in the normal standing position with your arms by your side and yourpalms facingyour thigh, andyou flex your elbow, your forearmmoves in thefrontalplane,andyouarestandingwitharms“akimbo”.Likewise,ifyouabductyourwholearmsothatitisparalleltothefloorandflexyourelbow,againthemovement is in the frontal plane. These three examples all involve elbowflexion, but the resultant action is very different. The true action of elbowflexion,aswithalmostallactions,isfromtheanatomicalposition.
Thetrueactionofelbowflexion,aswithalmostallactions,isfromtheanatomicalposition.
Allmovementsoccurinaplaneandaroundanaxis.
PlanesandAxes
Allmovementstakeplaceparalleltoaplane.Forexample,elbowflexion,spineflexion,kneeflexion,andhipflexionareall in thesagittalplane.Armand legabductionareinthefrontalplane,whilerotationsoccurinthehorizontalplane.Allmovementsalsotakeplacearoundanaxis(apointofrotation—likeanaxleofawheel),whichisatrightanglestotheplane.Forexample,allmovementsin
thesagittalplaneoccuraroundthefrontalaxis(refertoFigure1-1).
The aforementioned point can be illustrated by standing and flexing andextending thearmlikeapendulum. Ifyouusedapencil to indicate the“axle”aroundwhich thismovement occurs, the pencilwould be coming in from thesideintothemiddleoftheshoulder(perpendiculartothesagittalplane),whichwouldbethefrontalaxis.Now,standandabductandadducttheleg.Thepencil“axle”wouldcomeinfromthefronttothetopoftheleg(perpendiculartothefrontalplane),whichwouldbe thesagittalaxis.Finally, rotateyourhead fromrighttoleft.Wherewouldthepencilgotorepresentthe“axle”aroundwhichthismovementisoccurring?Thepencilwouldbecomingfromaboveintothemiddleofthetopofthehead,whichwouldbetheverticalaxis.
Thus, allmovements occur in a plane and around an axis. To summarize,movements in thesagittalplaneoccurarounda frontalaxis,movements in thefrontalplanearearoundasagittalaxis,andmovements in thehorizontalplaneoccuraroundaverticalaxis.

AnatomicalDescriptiveTerms
Thefollowingdescriptivetermsareprimarilyprefixesthatgobeforeotherroots.By knowing these terms, the meanings of words can be determined. Forexample, “cardio” refers to the heart; therefore a cardiologist is a physicianspecializing in the heart. Cardiovascular refers to the heart and circulation.Myocardiumreferstothemuscleoftheheart.Epicardiumistheinnermostlayerofthecoveringoftheheart.Epicardialfatisthefataroundtheheart,andsoon.Thisdeductivereasoningcanbeappliedwitheachoftheseterms.

AnatomicalRegions
Thefollowingterminologyrelatingtotheregionsofthebodyisveryimportantandishelpfulwhenworkingwithmusculoskeletalsystems.Thesetermsrefertoa part of the body and are used in many different contexts. For example,antibrachial refers to the areaof the forearm (belowor in front of the elbow).When someone speaks about drawing blood from the antibrachial region, thestethoscope diaphragm is placed in the antibrachial space when taking bloodpressure.Brachialisobviouslyabovetheantibrachialregion(abovetheelbow).Inthatregard,thebodyhasbothabrachialarteryandabrachialpulsewave.

BoneMarkings
As with the other terminology, bony markings are general terms referring tocharacteristicmarks on bones.When you learn the individual bones, the termusedisspecifictothatbone.Forexample,theenlargementontheproximalendof thehumerus is termeda tuberosity; theenlargementon theproximalendofthe femur is called a trochanter. This is the same description generally – anenlargementonabone,butdifferentspecifically,whenspeakingofaparticularbone.Thefollowingtermsareusedwhennamingbonymarkings:•Condyle.......asmooth,roundedprominencecoveredwitharticularcartilage•Crest................................aridge•Epicondyle..................aboveacondyle•Facet....asmall,smoothcartilagecoveredarea

FITNESSPROFESSIONALS’GUIDETOMUSCULOSKELETALANATOMYANDHUMANMOVEMENT–BONES
CHAPTER2•BONES
This chapter discusses bones andbonymarkings.Byvirtueof their name, theskeletal muscles attach to the skeleton and operate on the bone to causemovement. The markings on the bones (the bony markings) are the specificlocations where muscles attach. Four different types of bones exist have adefinitefunctioninthebody.
TypesandFunctionsofBones
TypesofBones
The human skeleton has four types of bones. Each type is described by itsgeneralshape:long,short,flat,andirregular.Thesenamesareverydescriptiveofwhateachtypeofbonelookslike.
•Longbones.Longbonesarelongandarecharacterizedbythefacttheyarelongerthantheyarewide.Theygenerallyhavetubularshaftsandarticularsurfacesateachend.Thefunctionof longbones is locomotion.Musclesoperatingonlongbonesallowyoutowalk,run,crawl,climb,jump,kick,andhit.Themajorbonesofthearmsandlegsarelongbonesthatincludethefemur,tibia,fibula,humerus,radius,andulna.
• Short bones. Short bones are shorter than long bones and also havegenerally tubular shafts and articular surfaces at each end. Short bonesallowflexibility.Forexample, the reasonyoucanmakea fist is that theshortbonesofthefingercan“roll”upintoafist.Theshortbonesinclude
allthemetacarpals,metatarsals,andphalanges.• Flat bones. Flat bones are flat and relatively thin and have broad, flatsurfaces.Their function isprotection. If thevitalpartsof thebodywerenamed,theywouldbethebrain,theheartandlungs,andthereproductiveorgans. All these vital parts are protected by flat bones. The brain iscompletelyencasedbythecranium(sixflatbones);theheartandlungsareprotectedby theflatbonesof theribcageandsternum; thereproductiveorgansareprotectedbytheflat¬bonedpelvicgirdle(theinnominate-threeflatbones).
•Irregularbones.Almostanybonethatisnotalongbone,ashortbone,oraflatboneisanirregularbone.Thesebonesarevariableinsizeandshape.They are generally compact in nature and are distributed throughout theskeleton.Theseincludetheentirevertebralcolumn,theeightcarpalbones,theseventarsalbones,andthepatella.
FunctionsofBones
As mentioned previously, bones have three primary functions – locomotion,flexibility, and protection. In addition, bones have three other very importantfunctions–theseadditionalfunctionsincludethefollowing:themanufactureofbloodcells;thestorageofdepositedofcalciumandphosphorus;andsupport.
•Bloodcellsaremadeinthemarrowofbones(intheircenters)andreleasedintothebloodstream.
•When a body doesn’t ingest enough calcium (as during pregnancy or inpostmenopausalwomen),thebodyusesstoredcalciumbytakingitfromthebones.This process has the effect ofweakening thebones,which iswhyitisimportanttogetenoughcalciumwhenthebody’sneedsarehigh.
•Theskeletonprovidesasupportfororgansandgivesshapetothebody.
BonyMarkings
Bonymarkings(whichareliterallymarkingsonthebone)maybecharacterized
byridges,depressions,holes,roughareasorsmoothareas.Thesemarkingsareusuallytheoriginorinsertionofmuscles.Bylearningthebonymarkings,alloftheoriginsandinsertionsofalloftheskeletalmusclescanbelearned.Drawingsof the bones showing the bony markings listed below are at the end of thissection.
Thebonesandthemarkingsoneachbonethatareusedwiththelocomotor(skeletal)musclesdiscussed in thisbookare listed in thefollowingsection,bybody region. The specific bonemarkings are noted below the bone onwhichtheyoccur.Bones thatdonothavebonymarkings thatareused for locomotormuscles havemarkings listed as “none.” This designation does notmean thatthese bones do not have markings, just that they are not important forlocomotion.Thenumberofbonespresentineachparticularbodyregion(part)isdenotedinparenthesisafterthenameofthebone.

Arthopolgy
Arthrology is that branch of anatomy that dealswith joints or articulations.Ajointorarticulationistheconnectionorjunctionbetweentwoormorebonesorbetweencartilageandbone.
ClassificationofJointsThreetypesofjointsexist–eachofwhichisdifferentiatedbyitsstructureandabilitytomove:❑Synarthrosisjoints(juncturaefibrosae)–immoveablejoints❑Amphiarthrosisjoints(juncturaecartilagineae)–jointswithslightmovement❑Diarthrosisjoints(juncturaesynoviales)–free-movementjoints•Synarthrosisjoints–twobonescomingtogetherbutwithnomovementbetweenthebones.Inmanycases,theboneshavefusedtogether.Threeexamplesofsynarthrosisjointsaretheinnominatebone,thesacrum,andthecranium.Theinnominateboneisthreebones(ischium,iliumandpubicbone)thathavefusedtogethertomakeoneinnominatebone.Thereisnomovementbetweenanyofthesebones.Wherethebonesjoin

•Amphiarthrosis joints – two bones coming together butwith very slightmovement between the bones. There are two types of amphiarthrosisjoints– symphysis (cartilaginous) joints and syndesmosis (ligamentous)joints. Two examples of symphysis joints are the symphysis pubis (thejunctionbetweenthetwopubicbonesthatmakeupthepubicarch)andthejunctionbetweentheupperpartofthesternum,themanubrium,andbodyof the sternum. In forced inspiration this joint allows the sternum to“bend”alittle.Anexampleofasyndesmosisjointisthecoraco-acromialjoint (a ligament that joins the coracoid process with the acromionprocess).
•Diarthrosisjoints–becauseofitsfreedomofmovementitisoftenreferredto as a true joint. Diarthrosis joints have several essential structures(characteristics), including the following: – Articular surfaces of bones.Theendsofthebonesaresmoothandcoveredwithcartilage.–Articularcartilage.Thecartilagecoveringtheendoftheboneprovidesasmooth,cushionedsurfacefortwobonestocometogether.
–Articulardisk.Adisk(ormeniscus)maybesituatedbetweendissimilarsurfacesinordertofacilitatefreemovement.
–Articularcapsule.Aligamentuscapsulesurroundsthejointandcontainssynovial fluid, which helps to lubricate the joint and serves as anutritientsource.
–Asynovialmembranelinesthearticularcapsulecontainingthesynovialfluid.
– Ligaments which run from one bone to the other which bind andstabilizethejoint.
There are six types of diarthrosis joints: 1. Gliding joint (arthrodia or
articulatio plana). A gliding joint involves bones that lie next to oneanother and as movement takes place, they glide (or slide or rub)together.Agoodexampleisthecarpalandtarsalbones,whichlienextto one another. When the wrist or ankle moves, these bones moveslightly against one another. This movement involves the intercarpalandintertarsaljoints,respectively.Anotherexampleofaglidingjointisthe movement between the head of the rib and the vertebra, or thejunctionoftheclaviclewiththesternum.
2. Hinge joint (ginglymus). The hinge joint is somewhat self descriptive,namelytwobonesactinglikeahingeonadoor.Hingejointsareprimarilyin one plane – flexion and extension. Good examples are theinterphalangeal jointsof thefingersand thehumerusandulna.Thekneeand ankle joints are also hinge joints, but are not as typical, since theyallowslightrotation.

5. Saddle joint (articulatio sellaris). In this joint, the opposing bones thatcometogetherareconvexandconcave.Thesurfaceofthejoint(bone)issaddle-shaped (like awestern saddle used in horse riding).The skeletononly has a few saddle joints. Saddle joints allow all movements exceptrotation. The best example of a saddle joint is the junction between the
first metacarpal (of the thumb) and the greater multangular (trapezium)carpal(carpo-metacarpaljointofthethumb).
6.Condyloidjoint(articulatioellipsoidea).Thisjointissimilartothesaddlejointinthatacondyleofonebonefitsintoanellipticalcavityofanotherbone, allowing all movements except rotation. The wrist joint with theradius and the scaphoid (navicular) carpal is an example of a condyloidjoint.Anotherexampleofacondyloid joint is theoccipitalboneand thesuperiorarticularprocessoftheatlas(firstcervicalvertebra).

MuscleClassifications
Because biologists are great classifiers, most parts of the body are classified.Nerves are classified, bones are classified, and muscles are classified.Classificationisnecessarybecausethebodyhasseveralkindsofmuscle,notjust
one.Theearlygrossanatomist, (i.e., the individualwhostudied thebodywiththenakedeye) classifiedmuscles according towhere theywere located in thebody.Intheprocess,hecameupwiththreebasicclassesofmusclesbylocation.
Those muscles that attached to the skeleton he termed skeletal muscles.Thesemusclesandthebonestowhichtheywereattachedformedaleversystemthat provided locomotion and movement. However, when he dissected theabdomen(theviscera),hefoundothermuscles.Thestomachisaholloworganwith six big flat muscles that help digest food that enters the stomach. Afterleavingthestomach,thefoodtravelsdownthirty-twofeetofintestine,whichhaslongitudinalandcircularmuscles in itswalls thatprovide theperistalticactionthatmovesthefoodthroughtheintestine.Becausethesemusclesdonotattachtotheskeletonbutarepresentintheviscera,henamedthemvisceralmuscles.
Much later, he discovered that blood vessels also have muscles in theirwalls. Although these muscles are not in the viscera, he classified them asvisceramuscles.Finally,whenthegrossanatomistexaminedtheheart,hefoundthatittooisamuscle.Becausetheheartisaveryuniquemuscle–differentthananyothermuscleinthebody,itformsaclassofmusclesallbyitself,thecardiacmuscle. Therefore, the first attempt to classify muscles involved groupingmusclesbytheirlocation.Inthisprocess,all themusclesofthebodywereputintooneofthreeclassifications–skeletal,visceral,andcardiac.
With the advent of themicroscope, a newbranch of biology began calledhistology. In thisprocess, the anatomist attempted todeterminewhat thebodylooked like under amicroscope.Microscopes enables the anatomist to closelyexamine cells,whether they are nerve cells, brain cells, bones cells ormusclecells.Subsequently, histologists developed a classificationofmuscles thatwasbased onwhat themuscle cell looked like, a process that produced away ofgroupingmusclescalledahistologicalclassification.
When the skeletal muscle was examined under the microscope, thehistologist saw that ithad lightanddarksegments that randown the lengthofthecells.Becausethesemusclesweresegmentedorstriated,heclassifiedthemas striated muscles. It just so happened that all skeletal muscles are striated.However, when he examined visceral muscles under the microscope, thestriations were missing – visceral muscles were non-striated. Accordingly, he
classified these muscles as smooth muscles. All visceral muscles are smoothmuscles. When he studied heart muscle under the microscope, it was againdifferentfromeitherof theother twotypesofmuscles.Ithadstriations.Thesestriations weren’t regular, like those of the skeletal muscles, they were criss-crossed in a network pattern. As a result, he classified heart muscle as asyncytium(multinucleated)orabranch-striatedmuscle.
Inotherwords,inadditiontoclassifyingmusclesaccordingtotheirlocation,the advent ofmicroscopes enabledmuscles to be classified according towhatthey look likeunder themicroscope.Similar to theirclassificationby location,all the muscles of the body can be put into one of three (additional)classifications–striated,smooth,andbranchstriated.
Anothermethodofclassifyingmusclesinvolvesnervecontrol.Muscles,likeall tissues of the body, are controlled by the nervous system.What kind of anerve innervates a particular muscle will affect whether the muscle can becontrolledvolitionally(atwill)orwhetheritiscontrolledautomatically.Musclesarealsoclassifiedaccordingtohowtheyarecontrolledbythenervoussystem.Ifamusclecanbecontrolledvolitionally,themuscleiscalledavoluntarymuscle.Most skeletal muscles are voluntary, although a few are both voluntary andinvoluntary.
Muscles that individuals have no control over are called involuntarymuscles.Mostofthebody’svisceralmusclesareinvoluntary,althoughtherearea few that arebothvoluntary and involuntary.When food is introduced to thestomach, the stomach muscles contract and start digesting food whether youwant them to or not. As such, stomach muscles are involuntary muscles.Likewise,thecardiacmuscleisaninvoluntarymuscle.Themusclesthatcanbebotharecalledvoluntary/involuntary(ormixed)muscles.Themusclesinvolvedin respiration are an example of mixed muscles. You can either breatheautomatically,orholdyourbreath.Table4-1summarizes the threemethodsofclassifyingmusclesandthethreecategoriesineachmethod.

MuscleProperties
Muscles have the following four properties or characteristics that make themunique: • Contractibility – the ability to shorten when innervated, causingmovement.Thisfactorisauniquepropertyofmuscles.
• Extensibility – the ability to be stretched beyond their normal restinglength.Thispropertyiswhatenablesflexiblemovementtooccur.
• Elasticity – the ability to rebound to their resting length after beingstretched.
•Tonicity–astateofhardnessofthemuscle.Whenamuscleisexercised,moremuscle fibersbecomeactive,and themusclebecomes firmer.Thisfactoriscalledmuscletone.Whiletheotherpropertiesofmusclescanbereadilymeasured,itisdifficulttoquantifytheleveloftonicity.
TypesofContractions
Contraction is a unique property of muscle tissue and involves the ability toshorten when innervated by a motor nerve. However, becausemore than onekind of contraction exists, muscle contraction is also classified by type. Inanatomy, two kinds of muscle contraction exists – isotonic contraction andisometric contraction. If a muscle shortens and causes movement when it isinnervated,thisisanisotoniccontraction.Forexample,ifyoumovea25-pounddumbbell from a table by curling it, your elbow flexors are isotonicallycontracting.Ontheotherhand,ifamuscleispreventedfromshorteningwhenitis innervated, this is an isometric contraction. For example, in the previousinstance,ifthedumbbellyouaretryingtocurlweighs400lbs(asopposedto25
lbs), and you try to curl it, but it doesn’t move, your elbow flexors arecontracting,butnotshortening,sincenomovementisoccurring.Inthisexample,yourelbowflexorsareisometricallycontracting.
When the fields of kinesiology, physical education, and sports medicinewereinitiallybeingestablished,manyindividualsinthesefieldsdiscoveredthattheyneededtoanalyzemuscularmovements.Becausetheyfoundtheanatomicalclassificationsomewhatlimitinginthisregard,theycreatedanewclassificationof muscular contractions. When a muscle was innervated and that muscleshortened and movement took place, they renamed isotonic contraction as“concentric contraction.”When themusclewas innervated andmovement didnottakeplace,thattypeofcontractionwascalleda“staticcontraction”insteadofanisometriccontraction.
Thetypeofmovement(term)thatwasneededthattheanatomistdidn’thavewas what happens when a muscle moves against gravity, but the musclelengthens during themovement.Using the previous example, if the 25-pounddumbbellonatableisactuallymovedwhenyouattempttocurl it,yourelbowflexorsare isotonicallyor concentricallycontracting. Ifyounowslowly returnthedumbbell to the table, then the samemuscles that curled thedumbbell areallowing it to be slowly returned to the table. Your elbow flexors arelengthening,butaredoingthework.Gravitywantstopullthedumbbellquicklyto the table. A kinesiologist calls this type of contraction an “eccentriccontraction.” Specifically, the muscle is working, but lengthening. If ananatomist were asked about this, he would say that your elbow flexors areactually slowly relaxing. Such an analysis is true, but someone analyzingmuscularmovementneedsadescriptivetermtouse.Inthisinstance,thattermis“eccentriccontraction.”
A mix of the aforementioned terms are employed in this book. When amuscle is working, but lengthening, this is referred to as an eccentriccontraction.Whenthemuscleisworking,butnotchanginglength,thisiscalledan isometric contraction.When the muscle is working and shortening, this iseitherdesignatedasanconcentriccontraction,ornodesignation isusedat all,sincethisisthetypicalmuscleaction.

NOTE:Sometimesamuscleisclassifiedastwodistinctmuscles—onereferredtoasamajor,theotherasaminor.Thedifference,however,isacademicinthatthe twopartshave thesameactionandareusually learnedas justonemuscle.For example, early anatomists divided the psoas muscle into two separatemuscles—thepsoasmajor(upperfibers),andthepsoasminor(lowerfibers),butthe muscle works as a whole. Likewise, the rhomboid major and rhomboidminor act as onemuscle and are usually learned as onemuscle.On the otherhand, onoccasion, the terms “major” and “minor” reflect two totally differentmusclesandmustbe treatedassuch,e.g.,pectoralismajorandminor,or teresmajorandminor.
Itisalsoimportanttonotethatsomemuscles,duetotheirextensiveorigin,haveopposite actions. In these instances, anatomists look at the actionsof theanteriorandposterior fibers thatare located inaparticularpartofamuscle todefinethatmuscle,e.g. theadductormagnus.Someof thesepartsaredifferentenoughtobeconsideredandstudiedastwoorthreemuscles,eventhoughtheyareonemuscle,e.g.,thedeltoidmuscle(refertopages121-123).Thedeltoidisonemusclebutcanbelearnedasthreemuscles:anteriordeltoid,middledeltoid,andposteriordeltoid.Theaforementionedthreetermsseparatemusclesarealsoreferred by some textbooks as the clavicular deltoid, acromional deltoid, andscapuladeltoid—termsthatcorrespondtotheirorigin.Althoughbooksdealwiththedeltoidasonemuscleandrefertoitasthemajorabductorofthearm,itmaybe beneficial to learn it as three muscles, because although the deltoid is anabductor of the arm, the anterior and posterior deltoids are arm adductors.Assuch,itishelpfultostudyandlearnthedeltoidasthreeseparatemuscles.

CHAPTER5•MOVEMENTANALYSIS
Thischapterdealswithananalysisofhumanmovements.Thechapterincludesabriefdescriptionofthethreerolesthatmusclestakeinaparticularmovement(primemovers,stabilizers,andneutralizers),alistofeverybodyactionwiththemusclesthatcontributetothataction,andfinallyadetailedmovementanalysisof selectedexercises andanoverviewof thebodyactions involved in specificactivities.
Analysis ofmovements divides amovement into a list of body actions.Amovementmaybeanexercise,sport,orsomeotheractivity.Initially,movementanalysis breaks up a particularmovement into specificmotions. For example,witharchery(shootinganarrow),themovementinvolvedcouldbebrokenintothe followingmotions: holding the bowout in front of you; pulling the stringbackandaiming;andreleasingthestring.Theidentifiedmotionsarethenrankedastothemostimportantfromastrengthperspective.Subsequently,eachmotionisthenbrokenupintoarankedlistofbodyactionsthatcomprisethatmotion.Inotherwords,movementanalysisinvolvesbreakingdownaparticularmovementinto rankedmotions, which are then broken into ranked body actions. In thisway,aconcise, completedescriptionof theoriginalmovement isderivedbyalistofrankedbodyactions.
RoleofMusclesinMovement
When analyzing the involvement ofmuscles in an activity or an exercise, thefollowing three terms are used to describe the role that muscles take in themovement–primemovers,stabilizers,andneutralizers.
•PrimeMovers
Aprimemoveristhemuscleormusclegroupthatdoesthemainmovement.Inthepush-up,forexample,theprimemoversaretheelbowextensorsandthearmflexors.Thesearethemusclesthatgetthebodyfromthe“floor”positiontothe“up” position. The elbow extensors straighten the elbow, and the arm flexorsbringthearmintothefinal“up”positionforthepush-up.Inpull-ups,theprimemovers are the elbow flexors and the shoulder extensors;both setsofmusclesmustworktogethertopullyoutothe“up”positionforapull-up.
Prime movers typically imply concentric contraction. In the movementanalysis of the various exercises and activities that appears in subsequentsectionsofthischapter,theprimemoveractionsaretypicallyforthefirstmotionlisted.
•Stabilizers
Usingthepreviouslydiscussedpush-upexampleasareferencepoint,ifyoulayonthefloorinthe“down”positionforthepush-up,andthenonlydidtheactionsoftheprimemovers,youwouldbeinthe“up”position,butyourbodywouldbesagging toward the floor (hyperextending thespineandhips).Agoodpush-upinvolveskeepingyourbodystraightorrigidwhenpushingtothe“up”position.Ifthebodyistobekeptstraight,thenmuscleshavetokeepitrigid.Themusclesthatmake thishappenarecalled stabilizers.Theystabilize thebody,while theprimemoversdo their job. In thepush-up, sincenostabilizerscause thespineand hips to be hyperextended, the stabilizers are the spine and hip flexors (topreventhyperextension).Dependingon theactivityormovement,musclescanbeeitherprimemoversorstabilizers.
Stabilizers typically imply isometric contractions. In the analysis of thevarious exercises and activities that appears in subsequent sections of thischapter,theactionslistedasisometriccontractionsusuallyinvolvestabilizers.
•Neutralizers
The third role ofmuscles inmovement is as neutralizers.Manymuscles havemorethanoneaction.Forexample,thebicepsisanelbowflexor,anarmflexor,and a supinator of the forearm. When it contracts, all of these actions areinitiated.Ifthemovementbeinganalyzedonlyinvolvessupination(forexample,drivingascrewintoapieceofwood),thenthebicepswillbeaprimemover(asone of the forearm supinators).However, of its three possible actions that thebiceps could undertake, only supination is needed. To prevent the other twoactions,muscleswiththeoppositeactionshavetobeinnervatedto“neutralize”theelbowandarmflexion,(inotherwords,theelbowandarmextensors).Inthisinstance,thesemusclesactasneutralizers.

APPENDIXB•BLANKDRAWINGS
This appendix includes blank skeletal sketches so that muscles and bonymarkings can be drawn on them. On the skeleton, the muscle can be drawnclearlyshowingtheoriginandinsertion.Suchadrawingcouldbedoneusingareferencecolor,e.g.,greenorigin(O)andblueinsertion(I),andthenthemusclecouldbeoutlinedinred.Thereasonseveralskeletaldrawingsareincludedissothatadrawingofonemusclewillnotoverlapothermuscles,therebyhidingtheoriginorinsertionofanothermuscle.Therefore,thetotalmusclecanbeseenandreviewedat aglance.Whilemostmuscle charts that appear in anatomybooksshow the surfacemuscles, the origin and insertion of thesemuscles is usuallyhiddenbyothermuscles.Bydrawingthemuscles,auniquereferenceforallthemuscles is provided that can be seen by just looking at the drawing. In otherwords,thesedrawingsshouldbethoughtofasasortof“musclecoloringbook.”
The individual bone drawings can be used to identify where a muscleattaches to that bone (either origin or insertion).Again, these reference pointscouldbecolor-coded.As such, thesedrawingswill tell theuserexactlywhereeachmuscle attaches to the bone. The belly of the muscle is not drawn, justwhereitattaches.Thisapproachprovidesausefulmethodofidentifyingwhetherthe individual doing the drawings knows the exact origin or insertion of aparticularmuscle.
Theindividualbonedrawingscanalsobeusedtoshowthelocationof thevariousbonymarkings.Rememberthatthebonymarkingareusuallytheoriginorinsertionofamuscle.Therefore,byknowingthebonymarkings,youarealsolearningtheoriginsandinsertions.
