Typical Locations and Effects of Adrenoreceptor Action Flashcards
1
Q
most vascular smooth muscle
A
alpha 1 and 2 (contraction - but mainly 1)
2
Q
pupillary dilator muscle
A
alpha 1 (contraction - dilates pupil)
3
Q
pilomotor smooth muscle
A
alpha 1 (erects hair)
4
Q
prostate
A
alpha 1 (contraction)
5
Q
heart
A
alpha 1 (increases F of contraction) Beta 1 (increases F/rate of contraction and increases renin release)
6
Q
postsynaptic CNS neurons
A
alpha 2 (multiple effects)
7
Q
platelets
A
alpha 2 (aggregation)
8
Q
adrenergic/cholinergic nerve terminals
A
alpha 2 (inhibit NT release) D2 (modulates NT release)
9
Q
fat cells
A
alpha 2 (inhibits lipolysis) Beta 3 (activates lipolysis)
10
Q
respiratory, uterine, vascular smooth muscle
A
Beta 2 (promotes smooth muscle relaxation)
11
Q
skeletal muscle
A
Beta 2 (promotes K+ uptake)
12
Q
human liver
A
Beta 2 (activates glycogenolysis)
13
Q
bladder
A
Beta 3 (relaxes detrusor muscle)
14
Q
renal smooth muscle
A
D1 (dilates renal blood vessels)
