Histology of Pancreas DSA Flashcards
how does the pancreas form
outpocketing from duodenum
-ventral and dorsal pancreas fuse
ventral bud of pancreas makes __
head and bile duct
dorsal bud of pancreas makes
part of head, neck, body, tail
blood supply to pancreas: islets
1) vascular component
- afferent arteriorle gives rise to capilary network lined by fenestrated endothelial cells
- venules leave islet supply blood to adjacent acini
blood supply of pancreas: exocrine pancreasq
independent vascular system
- acinar vascular system
- blood directly to exocrine pancreas
A cells secrete
glucagon
B cells secrete
insulin
d cells secrete
somatostatin and gastrin
what is somatostatins function
inhibit release of glucose and glucagon
F cells secret
pancreatic polypeptide
what is the function of pancreatic polypeptide
inhibit secretion of somatostatin
-inhibit secretion of pancreatic enzymes, blocks secretion of bile by stopping GB contraction
