Q

how do sympathetic and parasympathetic branch

A

sympathetic is highly branched; parasympathetic has fewer. widespread v. local effect

20
Q

what roots do sympathetic fibers come from

A

T1-L2/3

21
Q

what neurotransmitters are released by postsynaptic symp/parasymp

A

symp - norepinephrine (adrenergic)

parasymp - acetylcholine (cholinergic)

22
Q

where are the presynaptic symp neurons found

A

lateral or intermediolateral gray horn of cord

23
Q

what is the sympathetic trunk ganglia also called

A

paravertebral or chain ganglia and they are on both sides of the cord

24
Q

what carries the symp message from the cord to the sympathetic trunk

A

white rami communicans

25
Q

what supplies the eye

A

T1-2

26
Q

what supplies the head and salivary glands

A

T1-3

27
Q

what supplies the heart lungs and esophagus

A

T4-6

28
Q

what supplies the stomach liver gallbladder and pancreas

A

T7-9

29
Q

what supplies the small intestine

A

T8-10

30
Q

what supplies the appendix and colon

A

t10-11

31
Q

what supplies the rectum, bladder, and uterus

A

t12-l2/3

32
Q

what supplies the kidney

A

t11-l1

33
Q

what supplies the suprarenal gland

A

t10-l1

34
Q

what carries messages from the sympathetic trunk to the correct location

A

gray or post rami communicans

35
Q

how does the sympathetic innervate things that are above t1-l2/3

A

the white communicans can go up and down spinal levels before they synapse

36
Q

what is the role of the prevertebral ganglia? where is it

A

they are inhibitory neurons that inhibit muscles and glands in visceral organs; anterior to the verterbral column and only in abdomen and pelvis

37
Q

what do sympathetic fibers to the adrenal glands connect to

A

directly to the medulla, they attach to chromaffin cells which release epi and norepi

38
Q

what does the cranial outflow of the parasymp innervate

A

these are cranial nerves exiting the brainstem; organs of head, neck, thorax, and abdomen

39
Q

what does the sacral outflow of the parasymp innervate

A

they emerge from s2-4, the supply and innervate the organs of the pelvis and lower abdomen

40
Q

where are the bodies of the sacral outflow neurons located

A

visceral motor region of the gray matter

41
Q

what do the sacral outflow nerves form upon leaving the spinal cord

A

pelvic slanchnic nerves

42
Q

what distributes the sacral outflow

A

inferior hypogastric plexus

43
Q

what is cranial nerve 10

A

vagus n

44
Q

what innervates the GI

A

enteric nervous system; done by CN X (vagus) and pelvic splanchnic n

45
Q

what are the majority of spalnchnic nerves

A

sympathetic, except pelvic splanchnic

46
Q

what does the sympathetic use at pre/post synaptic neurons

A

ACh/Norepi

47
Q

what does parasymp use at their pre/post synaptic neurons

A

ACh for both
