Epithelial Tissue Characteristics
Covers surfaces Cellularity Polarity Attachment Avascularity Regeneration
Epithelial Tissue Functions
Protection
Controls permeability
Provides sensation
Produce specialized secretions
Basal Lamina
Thin non living material made of Epithelial Tissue and Connective Tissue
Lamina Lucinda
Bilayered, Clear Layer
Simple
Single
Stratified
Multiple
Squamous
Thin/Flat (more diffusion) (less protection)
Cuboidal
Squared shaped (moderate diffusion and protection)
Columnar
Tall slender rectangular (lots of protection not as much diffusion)
Simple Squamous Function
Reduces Friction, High Permeability
Simple Squamous Locations
Mesothelium, ventral cavities, Endothelium, lining of heart, blood vessels, inner lining of cornea, avieoli.
Stratified Squamous Function
Protection against pathogens, Chemical Attack, Abrasion
Stratified Squamous Locations
Surface of Skin, Lines Mouth, Esophagus, Throat, Rectum, Anus, Vagina
Simple Cuboidal Functions
