1
Q
alpha 1 receptors
A
stimulate contraction of smooth muscle
-constriction of vasculature smooth muscle
2
Q
beta 2 receptors
A
stimulate relaxation of smooth muscle
3
Q
muscarinic receptors
A
stimulate contraction of smooth muscle
-decrease in HR and contractility
4
Q
Beta-1 receptors
A
-on heart increase heart rate and contractility
5
Q
alpha-2 receptors
A
- in CNS
- inhibit further sympathetic activation
- decrease HR, BP etc
- suppress release of catecholamines
