metabolism and insulin Flashcards
pancreas anatomy: recognise the cellular structure and function of an islet of Langerhans
1
Q
what type of secretion are most pancreatic cells associated with
A
exocrine
2
Q
what are the endocrine cells within the pancreas
A
islets of langerhans
3
Q
what do a-cells make
A
glucagon
4
Q
what do b-cells make
A
insulin
5
Q
what do d-cells make
A
somatostatin
6
Q
what does glucagon do
A
increases blood glucose
7
Q
what does insulin do
A
decreases blood glucose (metabolic pathway), acts as a growth hormone (growth and development in mitogenic pathway)
8
Q
what does somatostatin do
A
calming down effect, reduces levels of insulin and glucagon
9
Q
what type of control are the islets of langherans under
A
paracrine
