Stratified Squamous Epithelium

Stratified Squamous Epithelium

structure - multiple layers of cells that are cubodial in the basal layer and progressively flattened toward the surface; the epithelium can be nonkeritanized (moist) or keratinized; in nonkeritanized stratified squamous epithelium, the surface cells retain a nucleus and cytoplasm, in keratinized stratified epithelium; the cytoplasm of cells at the surface is replaced by a protein called keratin, and the cells are dead

function - protection against abrasion, barrier against infection, reduction of water loss from the body

location - keratanized-skin; nonkeratinized(moist)-mouth, throat, larynx, esophagus, anus, vagina, inferior urethra, cornea

And there you have one (ONE!) of my notecards. Caleb said that I should have bought the english version of Anatomy & Physiology. I agree.

I love that you just taught me that nonkeratinized means moist- I think I am going to use that!

Wow. I thought you were taking college level A&P. I learned that stuff in like 6th grade or something. No, seriuosly, I got a little nauseous reading that. You go girl. You can do it. Your brain is still young and working. ;)
