Tissues

Epithelial • Connective • Muscular • NervousCredits

•Made up of cells that have grouped together.•All organs made up of it.•4 main kinds of tissues.

EpithelialConnectiveMuscularNervous

Epithelial Tissues

Simple • Stratified • Transitional • Home

•Covers surfaces in the human body•Protects, absorbs, filters, excretes and secretes•Has sensory receptors.•Three types:

SimpleStratifiedTransitional

Simple Tissues

Simple Columnar • Simple Cuboidal • Simple Squamous Pseuodostratified Columnar • Home • Back

•Made up of 1 layer.•Cells attach to a base.•Four types

Simple ColumnarSimple CuboidalSimple SquamousPseuodostratified Columnar

Simple Columnar Tissues• Used for secretion and

absorption.• Single layer of cells• Contains goblet cells• Found in:

Digestive Tract GallbladderUterus

Back • Home

Simple Squamous Tissues

• Single layer of flattened cells.• Cells shaped like discs.• Simplest tissue in the body.• Used for filtration and diffusion.• Found in:

Air Sacs of lungsBlood VesselsLymphatic Vessels

Back • Home

Pseuodostratified Columnar Tissues

• Single layer of cells.• Used for absorption and secretion.• Contains goblet cells and cilia.• Found in:

StomachBronchiGallbladder

Back • Home

Simple Cuboidal Tissues• Used for secretion and absorption

• Round nuclei in the center• Cube shaped cells• Single layer• Found in:

KidneysSmall GlandsOvaries

Back • Home

Stratified Tissues

Stratified Columnar • Stratified Squamous • Stratified Cuboidal Back • Home

•Made up of 2 or more layers of cells.•Three types of tissues.

Stratified ColumnarStratified SquamousStratified Cuboidal

Stratified Columnar Tissues• Cells are long and column-shaped. • Used for secretion and protection. • Made up of multiple layers.• Found in Vas Deferens.• Rarely found in body.

Back • Home

Stratified Squamous Tissues• Used in places subject to frequent abrasion.• Come in multiple layers.• Found in:

MouthVaginaSkinDry membranes

Back • Home

Stratified Cuboidal Tissues• Mostly found in only 2 layers.• Used for protection.• Found in:

Sweat GlandsMammary GlandsSalivary Glands

Back • Home

Transitional Tissues• Surface of cell is dome

shaped• Like both stratified

squamous and cuboidal tissues.

• Found in places like the bladder and urethra.

• Used for stretching. Back • Home

Muscular Tissues• Cells are able to contract.• Contains actin and myosin.• Cells slide past eachother,

allowing movement.• Three types:

SkeletalCardiacSmooth

Home • Skeletal • Cardiac • Smooth

Skeletal Tissues• Controls voluntary movements.• Cells contract causing body parts to move.

Attach bones and tendons.• Long cylindrical shapes.

Back • Home

Cardiac Tissues• Contracts to make the heart pump.• Moves blood throughout body. • Contracts involuntarily. • Found in the heart.

Back • Home

Smooth Tissues• Also known as visceral muscle.• Found in hollow organs.• Pushes substances through the body.

Ex: urine, baby, food

Back • Home

Nervous Tissues• Made of neurons which are

branching cells.• Used to transport signals from

receptors in the brain to parts of the body.

• Found in the brain, spinal cord and nerves.

Home

Connective Tissues• Most common tissue in the body.• Used for protecting, supporting and

binding parts of the body together.• Four Types:

BloodCartilageConnective Tissue ProperBone

Blood • Cartilage • Connective Tissue Proper • Bone • Home

Blood

• Made of red and white blood cells.• Mixed with plasma (matrix).• Found in blood vessels, veins, and arteries. • Transports nutrients and wastes throughout the

body. Back • Home

Cartilage• Three types:

ElasticHylineFibro Cartilage

Back • Home

ElasticMade of matrix and

collagen fibersCommonly found in

the earUsed for shape and

flexibility

Back • Home

Hyaline• Used for reinforcement and support• Resists stress and protects body• Made of firm matrix and collagen fibers

Back • Home

Fibro Cartilage• Used to absorb shock in places like the spinal

discs and knee joints • Contains a lot of fiber• Collagen is thick• Not very firm

Back • Home

Connective Tissue Proper• Large amount of matrix.• Two types:

DenseLoose

Back • Home

Dense• Used to connect

bones & muscles• Two Types

Dense RegularDense Irregular

Back • Home

Dense Regular•Parallel collagen and elastic fibbers •Makes up tendons and ligaments•Stands a lot of force if applied in one direction•Connects bones to muscle and muscle to bone

Back • Home

Dense Irregular

Very strongMade up of irregular collagen fibersFound in skin and digestive tractTake tension from any direction

Back • Home

Loose AreolarMade of matrix that has the consistency of gelMade of all types of fibersHolds extra fluidsUsed to protect:

organs bacteriainflammation

Back • Home

Loose AdiposeMade up of 3 different fibersTightly packed fat cellsNucleus is next to a drop of fatFound in abdomen and breastsInsulates body, protects organs, reserves fuel

Back • Home

Loose RecticularMade up of fibersFound in loose ground substanceRelys on a networkSupports cells (ex: White blood cells, mast cells and macrophages)Found in the spleen

Back • Home

Bone• Made of calcified, hardened collagen fibers.• Contains osteocytes inlacunae• Used for protection and support• Gives muscles leverage• Stores necessities
