EPITHELIAL TISSUES

Epithelial tissues are classified as either simple or stratifiedThe shape of epithelial cells are squamous, cuboidal, and columnar

Simple Squamous Simple Cuboidal Simple Columnar Stratified Squamous Stratified Cuboidal Stratified Columnar Pseudostratified Columnar Transitional

SIMPLE SQUAMOUS EPITHELIA

Composed of a single layer of flattened cells

Used for diffusion and filtration

Simple Cuboidal Simple Columnar Stratified Squamous Stratified Cuboidal Stratified Columnar Pseudostratified Columnar Transitional Epithelial

SIMPLE CUBOIDAL EPITHELIA

Made up of a single layer of cube-like cells with a large, spherical central nuclei

Function is secretion and absorption

Simple Squamous Simple Squamous Stratified Squamous Stratified Columnar

Stratified Cuboidal Pseudostratified Columnar Transitional

SIMPLE COLUMNAR EPITHELIA

Made of a single layer of tall cells with oval nuclei

Goblet cells are often found in this layer

Simple Squamous Simple Cuboidal Stratified Squamous Stratified Cuboidal Stratified Columnar Pseudostratified Columnar Transitional

STRATIFIED SQUAMOUS EPITHELIA

Thick membrane composed of several layers of cells

Forms external part of skin's epidermis and linings of the

Esophagus

Mouth

Vagina

Simple Squamous Simple Columnar Simple Columnar Stratified Columnar

Stratified Cuboidal Pseudostratified Columnar Transitional Epithelia

STRATIFIED CUBOIDAL EPITHELIA

Quite rare in the body

Usually found in the mammary glands and some sweat glands

Simple Squamous Simple Columnar Simple Cuboidal Simple Squamous Stratified Columnar Stratified Cuboidal Pseodostratified Columnar Tranditional

Epithelia

STRATIFIED COLUMNAR EPITHELIA

Limited distribution in the body

Simple Squamous Simple Columnar Simple Cuboidal Stratified Squamous Stratified Cuboidal Pseudostratified Columnar Transitional Epithelia

PSEUDOSTRATIFIED COLUMNAR EPITHELIA

Single layer of cells with different heights; some don't reach the surface

Nuclei are seen at different levelsSimple Squamous Simple Columnar Simple Cuboidal Stratified Squamous

Stratified Columnar Stratified Cuboidal Transitional Epithelia

TRANSITIONAL EPITHELIA

Basal cells are cuboidal

Surface of the cells are dome shaped
