Loading flashcards...
1

most vascular smooth muscle

alpha 1 and 2 (contraction - but mainly 1)

2

pupillary dilator muscle

alpha 1 (contraction - dilates pupil)

3

pilomotor smooth muscle

alpha 1 (erects hair)

4

prostate

alpha 1 (contraction)

5

heart

alpha 1 (increases F of contraction)
Beta 1 (increases F/rate of contraction and increases renin release)

6

postsynaptic CNS neurons

alpha 2 (multiple effects)

7

platelets

alpha 2 (aggregation)

8

adrenergic/cholinergic nerve terminals

alpha 2 (inhibit NT release)
D2 (modulates NT release)

9

fat cells

alpha 2 (inhibits lipolysis)
Beta 3 (activates lipolysis)

10

respiratory, uterine, vascular smooth muscle

Beta 2 (promotes smooth muscle relaxation)

11

skeletal muscle

Beta 2 (promotes K+ uptake)

12

human liver

Beta 2 (activates glycogenolysis)

13

bladder

Beta 3 (relaxes detrusor muscle)

14

renal smooth muscle

D1 (dilates renal blood vessels)
