functions of pseudostratified columnar cells

Back 9

secretes and propels mucus

Front 10

stratified squamous epithelium-keratinized

Back 10

multiple cell layers with cells becoming increasingly flat and scaly toward surface

stratified squamous epithelium

Front 12

functions of stratified squamous epithelium

Back 12

resists abrasion, retards water loss through skin, resists penetration by pathogens

stratified squamous epithelial-nonkeratinized

Back 13

same as keratinized epithelium but w/out the surface layer of dead cells

Front 18

functions of stratified cuboidal epithelium

Back 18

contributes to sweat secretion, secretes ovarian hormones, produce sperm

Front 19

transisitional epithelium

Back 19

resembles stratified squamous epithelium, surface cells are rounded, not flattened, often bulge at surface, may be flatter and thinner when epithelium stretch
