Physio: Adrenals Flashcards
1
Q
Main two stimulators of aldosterone production and release from the adrenal glands.
A
Angiotensin II
High plasma Potassium
2
Q
Main functions of cortisol.
A
Stimulate gluconeogenesis by:
- protein catabolism
- decreased glucose utilization
- increased lipolysis
Anti-inflammatory effects:
- induce lipocortin formation
- inhibit Phospholipase A2 and prostaglandin formation
- inhibit interleukin-2 production
- increased Ab release initially but eventually leads to lower Ab production
3
Q
Catecholamine effect on Liver, Skeletal Muscle, Adipose Tissue, and Pancreas
A
Liver: glycogenolysis, gluconeogenesis
SM: gylcogenolysis
AT: glycogenolysis, lipolysis
Pancreas: inhibition of insulin secretion, stimulation of glucagon
