TissuesTissues
• Groups of cells that have similar functions and structures
• Epithelial• Muscle• Connective• Nervous• Align cells to cover and
protect them
Epithelial Connective Muscle Nervous Credits
EpithelialEpithelial
Classified by the number of layers
Classified by shape
Glandular Simple Stratified Home
SimpleSimple
Consist of one layer of cells
Covering epithelia Lining epithelia
Pseudostratified Squamous Cuboidal Columnar epithelia home
PseudostratifiedPseudostratified
Actually a simple columnar epithelium
Gives the false appearance of being stratified
Is often ciliated
Simple Epithelial Home
ColumnarColumnar
A classification of epithelium
Depends on shape Can be nonciliated Can be ciliated
Simple Epithelial Home
StratifiedStratified
Consists of two or more layers of epithelial cells
Covering epithelia Lining epithelia
Transitional Squamous Cuboidal/Columnar Epithelial Home
TransitionalTransitional
Stratified squamous epithelium
Has rounded cells Has the ability for cells
to slide over one another to stretch an organ
Stratified Epithelial Home
Cuboidal/ColumnarCuboidal/Columnar
Classification of epithelium depending on shape
Not common in the body
Stratified Epithelial Home
Connective TissuesConnective Tissues
Found in all parts of the body Most abundant and widely
distributed of tissues Most have a large amount of
blood vessels Composed of many types of
cells Made up of noncellular and
nonliving material called a matrix
Proper Cartilage Bone Blood Home
CartilageCartilage
Cartilage protects bones
Cartilage helps form bones
Found in the knees, ears, and nose
Hyaline Elastic Fibrocartilage Connective Home
HyalineHyaline
Has chondrocytes in lacunae
Found in:◦ Embryonic skeleton◦ The end of long bones◦ Nose◦ Trachea◦ larynx
Cartilage Connective Home
FibrocartilageFibrocartilage
Cartilage Connective Home
•Provides tensile strength
•Absorbs compression shock
BoneBone
Proper Dense Connective Home
•Stores calcium
•Stores minerals
•Stores fat
•Marrow inside of bones is the site of hematopoiesis
ProperProper
Loose Areolar Adipose Reticular BoneConnective Home
•Embryonic•Includes:
–Areolar–Adipose–Reticular–Dense fibrous connective tissues
AreolarAreolar
Bone Connective Home
•Considered the prototype of the connective tissues
•All other connective tissues are based off of the structure of the areolar connective tissues
ReticularReticular
Bone Connective Home
•Loose ground substance•Forms a soft internal skeleton•Resembles fibroblastsSupports many free blood cells in lymph nodes, the spleen, and bone marrow
DenseDense
Regular Irregular Elastic BoneConnective Home
•Often referred to as dense fibrous connective tissues•Fibroblasts•Includes:
–Regular fibers–Irregular fibers–Elastic fibers
IrregularIrregular
Bone Connective Home
•Fibroblasts
•Found in dermis
•Sub mucosa of the digestive tract
•Fibrous organ capsules
ElasticElastic
Bone Connective Home
•Combine strength with elasticity •Dense fibrous tissues
•Occurs in regular and irregular connective tissues
BloodBlood
Connective Home
•Closed circulatory system in humans
•Open circulatory system in other animals
MuscleMuscle
Voluntary Involuntary Home
•Produces most types of body movements•Three main types of subcategories of muscle tissues are:
–Cardiac–Skeletal–smooth
InvoluntaryInvoluntary
Smooth Cardiac Muscle Home
•Unconsciously controlled movements of the body
•Happens without humans being aware
SmoothSmooth
Muscle Home
•Mainly found in the walls of hollow organs
•Normally two layers that run perpendicular to each other
NeuronsNeurons
Sensitive Highly specialized Receives and sends
stimuli to the brain and the whole body
Nervous Home
