TISSUES
•Tissues are groups of cells similar in structure and function
Epithelial Connective Muscle Nerve

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