A

contraction, a1

34
Q

GI Tract: Smooth Muscles: Sphincters - cholinergic response and receptor

A

relaxation, M3

35
Q

GI Tract: Secretion - adrenergic response and receptor

A

decreased secretion, a2 (don’t need digestive juice)

36
Q

GI Tract: Secretion - cholinergic response and receptor

A

increased secretion, M3 (need digestive juice)

37

Liver - adrenergic response and receptor

A

glycogenolysis and gluconeogenesis, a1, B2

38
Q

A

lipolysis, a1, B1, B2, B3

39
Q

Kidney - adrenergic response and receptor

A

increase renin secretion, B1

40
Q

Pancreas - adrenergic response and receptor

A

decrease insulin, a2

41
Q

Eye: Iris: Radial Muscle - adrenergic response and receptor

A

contraction, a1 (mydrasis=pupil dilation)

42
Q

Eye: Iris: Circular Muscle - cholinergic response and receptor

A

contraction, M3 (miosis=pupil constriction)

43
Q

Eye: Ciliary Muscle - adrenergic response and receptor

A

relaxation, B2 (relaxing ciliary muscle = closing drainage = more intraocular pressure)

44
Q

Eye: Ciliary Muscle - cholinergic response and receptor

A

contraction, M3 (contracting ciliary muscle = opening drain = less intraocular pressure)

45
Q

Eye: Ciliary Epithelium - adrenergic response and receptor

A

increased secretion, B2 (makes more aq goo)

46
Q

Eye: Lacrimal glands - adrenergic response and receptor

A

mucus and enzymes, a1

47
Q

Eye: Lacrimal glands - cholinergic response and receptor

A

watery tears, M3

48
Q

SNS and PSNS typically oppose each other, EXCEPT when it comes to _________

A

male sex organs
SNS - ejaculation, a1
PSNS - erection, M3

49
Q

______ and ______ are controlled by SNS only

A

arteries and veins

50
Q

Pilocaprine Mechanism

A

M3 agonist, contracts ciliary muscle and allows for drainage (decreases intraocular pressure)

51
Q

Brimonidine Mechanism

A

a2 agonist, ciliary body inhibits production of aq goo and increase drainage (decreases intraocular pressure)

52
Q

Timolol Mechanism

A

B antagonist, inhibits secretion of aq goo from ciliary epithelium (decreases intraocular pressure)

53
Q

Latanaprost Mechanism

A

prostaglandin PGF2 analog, increase drainage of aq goo (decreases intraocular pressure)

54

What is this?

A

ACh

55

postganglionic neurons is

A

NE

63

Primary transmitter of all preganglionic neurons is

A

ACh

65
