Autonomic NS

Question 1

What are the main neurons of the ANS classified as and where are their ganglia located and are they mylinated

Answer 1

multipolar
outside brain and spinal cord
preganglionic-unmylinated
postganglionic-mylienated

Question 2

innervation targets of somatic NS and Autonomic NS

Answer 2

Somatic- efferent voluntary motor n (skeletal striated m)

Autonomic- Involuntary motor n (smooth m, cardiac, glands)

Question 3

what are the 3 divs of the ANS

Answer 3

Sympathetic
Parasympathetic
Enteric

Question 4

where are the preganglionic sypathetic neurons found

Answer 4

T1-L3 spinal cord seg (lat horns)

Question 5

where are the preganglionic parasympathetic neurons found

Answer 5

Cranial outflow (CN3,7,9,10)
Sacral outflow s2-4

Question 6

what innervates the sup, mid and inf cervical sympathetic gangion

Answer 6

axons from t1-3

Question 7

what innervats l4-co sympathetic ganglion

Answer 7

axons from l1-3

Question 8

path of sympathetic axons out of spinal cord

Answer 8

start in lat horn exit out ant root and join trunk

exit as white communicating ramus (unmyl) and syapse on ganglai then exit as grey communicating ramus (mylin)

Question 9

all 3 cervical ganglia send branches to this

Answer 9

cardiac plexus

Question 10

what ganglia primarly inn the head and neck

Answer 10

cervical sympathetic ganglion

Question 11

parasympathetic cranial nerves are

Answer 11

CN 3,7,9,10

Question 12

what ganglia doe the parasympathetic nerves inn

Answer 12

cillary (eyes)
pterygopalantine (lacramal)
otic (parotid)
submandibular (sublingual, submandibular)
vagus (many visceral items)

Question 13

what CNs inn the cillary, pterygopalantine, Otic and Submandibular ganglia

Answer 13

Cillary- CN3
Pterygopalantine- CN7
Otic- CN9
Submandibular- CN7

Question 14

what is horners syndrome caused by

Answer 14

Blockage of int carotid sym nerve plexus in cavernous sinus ( causes sympathetic to get cut off so parasympathetic takes over )

Question 15

what does horners syndrome present as

Answer 15

dialation
drooping eyelid
hypersecretion of lacrimal gland

Question 16

response of sympathetic system

Answer 16

1. increased cardiac output
2. increased blood glu levels
3. Activation of sweat glands
   4-vasoconstriction in organs (except mus)

Question 17

response of parasympathetic system

Answer 17

1. increased secretion of saliva, mucus, dig enzymes
2. increased glandular sec
3. Activation of smooth mm
