Document Summary

Epithelium tissue: protective covering of surfaces (inside/outside) of body. Has free (apical)=lumen, basal=attached to basement membrane, and lateral (cells touch one another) surfaces. Basement membrane- attached to basal surface, formed by secretion of epithelium/connective tissue. Avascular (no blood supply), and capable of regeneration (damaged cells replaced) Microvilli: (brush border): increase surface area for absorption/secretion. Classification of epithelium (diagrams bout this as well) Simple: one layer of cell, all contact basement membrane. Pseudo stratified: tissues appear stratified, but contact bm, only one layer. Simple: allows diffusion of gas, filtration of blood, secretion/absorption. Cuboidal/columnar: secretion/absorption may have goblet cells secreting mucus. Simple cuboidal: single layer, cube shaped cells, some have villi/cilia. Glands, auditory tubes, uterus, bile ducts, ventricles of brain. Movement of particles out of bronchioles, aids in movement of oocytes, absorption by cells of intestine. Stratified squamous: multiple layers, cuboidal in basal layer, flatten at surface. Pseudo stratified columnar: cells reach b. m. , usually ciliated, associated w/ goblet.
