Released by which gland?

adrenal glands
effects on which receptors

α 1 and 2, β 1 and 2 receptors
what effects?
(skeletal muscle; cardiac; skin & kidney)
- - on β 2 receptors in skeletal muscle vessels -> vasodilation
- - Increase cardiac output and total peripheral resistance
- - Vasoconstriction in the skin and kidneys causing a narrow pulse pressure
Actions of α adrenergic receptors:
- - Inhibits insulin secretion by the pancreas
- - Stimulates glycogenolysis in the liver and muscle
