Created by cells with similar shapes and functions

Creates “the Fabric” the Body

Composed of Epithelial, Muscle, Nervous, Connective

Epithelial Connective Muscle Nervous Credits

Almost entirely composed of cells

Can be divided into Simple and Stratified Epithelium

Classified by the number of cell layers and the cell shape

Home Simple Epithelium Stratified Epithelium

Consists of single-celled layers

Main functions consist of absorption and filtration

Has three primary shapes

Contain a sparse cytoplasm

They consist of single flattened cells

Specialize in diffusion and filtration

Divided into two sections

Home Simple Cuboidal Simple Columnar Psuedostratified Columnar Mesothelium Endothelium

Consists of a cube-like shape

Contain one large spherical central nuclei

Primary functions include secretion and absorption

Home Simple Squamous Simple Columnar Psuedostratified Columnar

Creates a slick, friction reducing lining

Found in hollow organs of cardiovascular system

Allows the exchanges between blood streams and tissue cells

Home Mesothelium

Found in the serous membrane

Lines the ventral cavity

Covers organs

Home Endothelium

Contains closely packed cells Located in areas of the

digestive tract Associated mostly with

absorption and secretion

Looks as if many cell layers are present

May or may not contain cilia and goblet cells

Location depends on characteristics

Have two more cell layers

Main concerns include protection

Identified by apical layer

Home Stratified Squamous Stratified Cuboidal Stratified Columnar Transitional

Most commonly found of all stratified epithelia

Main functions include protection

May or may not contain keratin

Home Stratified Cuboidal Stratified Columnar Transitional

It is rare to find in the body Found in the ducts of larger

glands Consists of only two layers

Home Stratified Squamous Stratified Columnar Transitional

Not commonly found in the body

It is located in smalls amounts in specific areas of the body

Usually found in junctions of two other types of epithelium

Home Stratified Squamous Stratified Cuboidal Transitional

They have the ability to alter their shape

Basal cells are cuboidal or columnar

Apical layer consists of domelike or squamous shaped cells

Home Stratified Squamous Stratified Cuboidal Stratified Columnar

They are highly cellular

Responsible for much of body’s movement

Three different types

Home Skeletal Muscle Cardiac Muscle Smooth Muscle

Attach to bones of the skeleton

Forms the body’s flesh

Allows the body to voluntarily create movement

Home Cardiac Muscle Smooth Muscle

Found only in the walls of the heart

Creates intercalated discs

Aids in propelling blood throughout the entire body
