Types shape
Epithelial classification
Number of layers(Simple Vs. Stratified) and shape (Squamous Vs. Cuboidal Vs. Columnar)
Simple
Single layer of cells. Allow for diffusion, osmosis, secretion, excretion, absorption, filtration.
Stratified
For protection (skin), multiple layers on top of each other
-
-
-
-
Transitional
Cells appear one way, but change shape under different conditions
..
Glandular Epithelium
Cells lie in clusters deep to covering and lining epithelium, produce secretions. (Glands)
Endocrine Glands
Secretions(Hormones) enter the interstitial fluid and diffuses directly into blood stream with out flowing into a duct
Exocrine Glands
Cells produce a secretion into duct system that empties directly on surface of body or into a cavity (Sweat). Unicellular Vs. Multicellular. Simple Vs. Compound. Tubular Vs. Acinar Vs. tubuloacinar.

Types of Cell junctions(5)
Tight Junctions, Adherens Junctions, Desmosomes, Herhidemosomes, and Gap Junctions
Gap Junction
Connexons connect neighboring cells to rapidly move energy or electricity to other cells. "Tunnels"
-
Epithelium Tissue
Closely packed cells arranger in continuous sheets that form the outer covering of body, line body cavities and cover some internal organs. Avascular, and reproduce readily.
