BODYTISSUES Anatomy Notes EPITHELIAL TISSUES: Locations: Body coverings, Body linings, Grandular tissue groups of cells with similar structure and Function o Foor primary types ★ Epithelial tissue (Epithelium ★ Connective tissue Muscle tissue Nervous tissue Apical Surface SIMPIE Basal Surface Apical Surface STRATIFIED Basal surface Functions: protection, Absorbtion, filtration, Secretion. EPITHELIUM CHARACTERISTICS *Cells Fit closely together and often form sheets The apical surface is the free surface of the tissue The lower surface of the epithelium rests on a basement membrane Avascular (no blood supply) Regenerate easily if well nouris ned Somos Cubadal Columnar Classification based on cell shape SIMPIE EPITHE LIA: Simple Squamous Single layer of flat cells Location-usually forms membranes lines longs and Capillaries Function in diffusion, filtration, or secretion in membranes.
