Q

what are the 4 pathways presynaptic sympathetic nerve fibres can take in the sympathetic trunk

A

innervation of abdominopelvic viscera

24
Q

what do post synaptic sympathetic fibres from the pre-vertebral ganglia form

A

periarterial plexuses which follow branches of abdominal aorta to reach destination

25
Q

parasympathetic outflow

A

craniosacral

CN 3 7 9 10 (III, VII, IX and X) and S2-4

26
Q

CN III provides motor fibres to where

and parasympathetic fibres to where

A

motor - extra-ocular muscles

PS - ciliary muscle and sphincter pupillae

27
Q

CN III parasympathetic innervation of the ciliary muscles in the eye does what

A

accommodation - causes lens to thicken to see closer in

28
Q

CN III parasympathetic supply of sphincter pupillae does what

A

constricts pupil

29
Q

CN VII provides parasympathetic innervation to where

A

lacrimal, submandibular and sublingual glands

30
Q

CN VII provides motor innervation to where

A

muscles of facial expression

31
Q

what branch of CN VII provides parasympathetic innervation to the submandibular gland

A

chorda tympani

32
Q

what are the 5 branches of the facial nerve in the face

A 
temporal
zygomatic
buccal
marginal
cervical
33
Q

what does CN IX provide parasympathetic secretomotor supply to

A

parotid salivary gland

34
Q

where does CN X provide parasympathetic sensory and motor supply to

A

smooth muscle of organs of thorax, abdomen and up to left colic flexure in abdomen (foregut and midgut)

35
Q

S2,3,4 supply parasympathetic innervation to where in the gut

A

descending colon, sigmoid colon and rectum

36
Q

s2 3 and 4 form what

A

pelvic splanchnic nerves

37
Q

pelvic splanchnic nerves supply what

A

organs of the pelvis

38
Q

are there any parasympathetic nerves to the body wall

A

no - except erectile tissue of genitalia

39
Q

parasympathetic nerves tend to have ____ presynaptic fibres and _____ postsynaptic fibres

A

long presynaptic

short postsynaptic

40
Q

sympathetic nerves tend to have ___ presynaptic fibres and ___ postsynaptic fibres

A

short presynaptic

long postsynaptic

41
Q

are parasympathetic fibres part of spinal nerves

A

no except s234

42
Q

where are parasympathetic post synaptic cell bodies located

A

in or on wall of target organ

43
Q

visceral parasympathetic sensory supply mostly from

A

CN IX
CN X
S2-4

44
Q

what nerve provides parasympathetic innervation of chemoreceptor and baroreceptors in neck arteries and receptors in pharynx

A

CN IX

45
Q

what nerve provides parasympathetic innervation of cervical viscera and vessels and viscera in thorax and abdomen

A

CN X

46
Q

visceral sensory from pelvic viscera and distal colon carried in

A

S234

47
Q

parasympathetic sensory component does what

A

monitors normal physiological processes and reflex activities

48
Q

what cranial nerve gives fibres to the pterygopalatine ganglion and submandibular ganglion

A

CN VII

49
Q

what cranial nerve gives fibres to the otic ganglion

A

CN IX

50
Q

what does sympathetic stimulation do to blood vessels

A

constriction

51
Q

what is referred pain

A

when body interprets visceral pain as somatic pain i.e. from body wall of spinal segment rather than organ

52
Q

pain in the somatic system is highly

A

localised

53
Q

describe the feeling of appendicitis

A

patient feels a diffuse pain around umbilicus (T10) then moves to RLQ as appendix starts to irritate body wall

54
Q

sympathetic stimulation of heart

A

increases rate and strength of contraction

dilate coronary vessels

55
Q

parasympathetic stimulation of heart

A

decreases rate and strength of contraction

constricts coronary vessels in relation to reduced demand
