Pancreas
Two cell types to produce:
exocrine acini produce:
islets
of
Langerhans produce:
1 – 2% of pancreas are the islets of
LangerhansSlide5
Islets of
Langerhans
Two hormones are produced:
beta cells:
alpha cells:
blue = cell nuclei
green = insulin
red = glucagonSlide6
Insulin Function
When is insulin released? after eating
hyperglycemia
beta cells
cellular signals for insulin release
decreased blood sugar
increased glucose uptake
glycogen production in liverSlide7
Glucagon Function
What does glucagon do? breaks down glycogen
hypoglycemia
alpha cells
cellular signals for glucagon release
increased blood sugar
glucose release from liver
glucose production in liverSlide8
