Adrenergic receptors

Question 1

adrenergic receptor location

Answer 1

ANS effector organs

Question 2

Noradrenaline

Answer 2

endogenous transmitter released from synapses

Question 3

adrenaline

Answer 3

hormone from adrenal medulla

Question 4

dopamine

Answer 4

NA precursor but endogenous transmitter in CNS

Question 5

Alpha 1 adrenergic receptor

Answer 5

Gq linked
-Constricts SM except for Gastrointestinal tract
-causes glycogen-lysis (increase metabolism)

Question 6

Alpha 2 adrenergic receptor

Answer 6

Gi linked
- relax gastrointestinal tract
-depresses further adrenergic and cholinergic releases

Question 7

Beta 1 adrenergic receptor

Answer 7

Gs linked
-Has strong effect on increasing heart rate and contraction

Question 8

Beta 2 adrenergic receptor

Answer 8

Gs linked
-relaxes most SM
-causes tremor and muscle mass/ contraction force
-inhibits histamine release
-stimulates further adrenergic release

Question 9

Beta 3 adrenergic receptor

Answer 9

Gs linked
-relaxes bladder
-increase anabolic metabolism
