The Pancreas (card 3); (see slide for cell illustrations)
*Pancreatic hormones act under Humoral control of glucose concentrations in the blood.
Endocrine functions of the Pancreas.
-Pancreatic islets (of Langerhans) contain alpha, beta, & delta cells. (endocrine islets = AgBi/D cells)
-Give each of their functions.
1) Alpha: glucagon --> glycogen breakdown (liver releases glucose), increased blood glucose levels (BGL).
2) Beta: insulin --> glucose uptake, decreasing blood glucose levels (BGL).
- 3) Delta: produce Somatostatin (GH inhibiting hormone)
- -Inhibits secretion of glucagon & insulin
