striated duct

Question 4

what are acini cells surround by?

Answer 4

myoepothelial cells

Question 5

what is the function of my-epithelial cells?

Answer 5

contractile function- push salivary along ducts

Answer 7

-prominant basal nuclei
-stain dark pink
-granular

Question 8

what are the features of mucous acini? (sublingual)

Answer 12

sublingual

Question 13

what is the purpose of striated folds?

Answer 13

gives a larger surface area for exchange

Question 14

where is the nucleus in striated cells?

Answer 14

basal-but striated ends make it look like its not

Question 15

what is the purpose of striated ducts?

Answer 15

modification of saliva

Question 16

what size is the lumen of striated cells?

Answer 16

large lumen

Question 17

what are the features of secretory cells?

Answer 17

-large lumen
-pseudostrafied until gets to oral epithelium where it becomes stratified and merges with oral epithelium
