1
Q
Very important in cutaneous-level thermoregulation
A
AV shunts
arterioles–>venules
2
Q
Preganglionic sympathetic nerves release which neurotransmitter
A
ACh
3
Q
ACh acts on nAChR to depolarize postganglionic nerve, releasing what?
A
norepinephrine
4
Q
Norepinephrine causes what?
A
vasocontriction
5
Q
What receptor type does norepinephrine use?
A
alpha-1
6
Q
________ from the ________ nerve causes vasodialation
A
ACh
7
Q
Postganglionic sympathetic ACh release uses which type of receptor to cause vasodialation?
A
G-protein coupled–>NO synthesis
8
Q
ACh activates what type of sweat glands?
A
eccrine
9
Q
Norepinephrine activates which type of sweat glands?
A
apocrine
10
Q
Mechanism of sweat gland secretion
A
NKCC pump
11
Q
