functions of gingiva
protection
-mechanical
-bacterial
-chemical
-prevent dehydration ~ barrier
sensation - innervated
secretion - thru muscosa
thermal regualtion
what oral mucsoa made up of
epithelium
connctive tissues - lamina propria
3 types mucosa
- masticatory - tough exits around hard plalate ~ chewing
- lining - flexible
- specialsied mucosa - gustatory msucoa - receptors senstion taste
ginigiavl mucosa
masticatory muscosa
thick epithelium
keratinsied - gives mechanical resistance
pink
