Document Summary
Tissues four kinds of tissues: epithelial, nervous, connective, and muscular. Tissues are groups of similar cells that perform together to serve a specialized function. Structure of epithelial sits on top of basement membrane. (figure 2) Thin extracellular layer that separates epithelial from underlying connective tissues. Acts as regulator for movement of molecules to deeper connective tissues. Acts to anchor epithelium to underlying connective tissues. Shape: squamous irregular sides flat, thin and wide, cubodial thicker and cubes, columnar column looking like (long skinny) Layers: simple one single layer, stratified multiple layers. Simple cuboidal absorption (nephron, kidneys) water absorption is most optimal. Simple columnar: non-ciliated microvilli increases surface area for better absorption and secretion, goblet cells to produce mucin (digestive, ciliated hair like projections (goblets present) uterine and respiratory tract. Stratified squamous adopted for protection (epidermis of skin) Stratified cuboidal protection, lining of ducts and glands (exocrine) Stratified columnar deep and plenty of protection, (male uretha and front of eyeball)
