ANAT 416 Lecture Notes - Lecture 5: Pancreatic Polypeptide, Mecha, Genetic Disorder
Jan 24 // lec 5 // pancreas 1 // jl liu. Current research directions to try to regenerate pancr for type i diabetes. Pancr gland is attached to spleen + duod, under liver/behind stomach. Rabbit, pancr is diffused, not 1 physical thing. Share blood vessels with spleen due to physical proximity. Acini = duct ends, contain acinar, centroacinar, and ductal cells. Islets in ocean of acinar cells, are the endo cells. F x. pancr as exocrine and endocrine organ, by cell secr. Tons of rer and golgi structures for intense secretions. 1/2 litre of pancr fluid is secreted every day by acinar/ductal cells. Centroacinar cells: diff morphology, found between acinar and ductal cells. Buffers gastric acid by making electrolytes, mucins, hco3- Rich capillary structure, high vascularization for hormone secr. Get blood from 2 artery branches splitting from celiac trunk. Venous: same, but the splenic, inferior/superior mesenteric veins join to form hepatic portal vein also.
