Autonomic Receptors Flashcards
1
Q
Alpha 1
A
Smooth Muscle Constriction
(Vascular, ureter, bladder sphincters)
2
Q
Alpha 2
A
Presynaptic SNS nerve endings- Inhibits norepinephrine release
Brain- Neurotransmission
Think precedex
3
Q
Beta 1
A
Heart
Increase rate, contractility, conduction
4
Q
Beta 2
A
Blood vessel- Dilation
Bronchioles- Dilation
5
Q
D1
A
Blood vessels
Dilation
6
Q
D2
A
Presynaptic SNS nerve endings- inhibition of NE release
7
Q
M1
A
Skeletal nerve endings- Facilitate Ach release
Also in airway
8
Q
M2
A
Lung
-Located Presynaptically and function as negative feedback to limit release of ACh
9
Q
M3
A
Lung smooth muscle-
Located post synapse and mediate bronchoconstriction
10

N1
A
PNS & SNS ganglion
Ganglionic blockade
11
Q
N2
A
Skeletal muscle
Muscle contraction
