Autonomic Nervous System

Question 0

The main sympathetic innervation to the head comes from ____ in the spinal cord

Answer 0

T1

Question 1

Autonomic information is regulated by the______ at the presynaptic neurons

Answer 1

hypothalamus. information comes down from hypothalamus to regulate the presynaptic neurons

Question 2

Describe how sympathetics get into the head

Answer 2

from intermedolateral cell column T1
ascend sympathetic chain to the cervical ganglion.
all preganglionic sympathetic fibers are in the chain
all postganglionic sympathetic fibers will distribute from the chain

Question 3

What do we mean when we say that the cervical sympathetic ganglia are distribution cneters of postganglionic sympathetic fibers

Answer 3

whaever that ganglion is, that’s where post sympathetic gets distributed,
that ganglion takes care of tis “territory”

Question 4

Cervical ganglion that is always present

Answer 4

superior cervical ganglion

Question 5

The cervical sympathetic trunk or chain is ______ to the common carotid and _______ to prevertebral fascia

Answer 5

posterior

embedded in or deep to

Question 6

The superior cervical ganglion’s distribution is

Answer 6

sympathetics to the head.

Question 7

Superior cervical ganglion sends off _____ nerve and _____plexus

Answer 7

internal carotid N

internal carotid plexus

Question 8

all ganglia give off

Answer 8

perivascular plexuses

Question 9

Branches from the internal carotid plexus (4)

Answer 9

perivascular plexuses
sympathetic branch to the ciliary ganglion
deep petrosal nerve
carotico-tymmpanic nerve

Question 10

postganglionic fibers that continue to course along tunica adventitia of verebral bloodvessels

Answer 10

perivascular plexuses

Question 11

Deep petrosal nerve joins_________ nerve to form_______nerve

Answer 11

greater petrosal nerve

vidian nerve

Question 12

Vidian nerve innervates

Answer 12

sympathetics to the palate, nasal cavity, pharynx, orbit and lacrimal gland

Question 13

When you disturb an artery in the cervical area, what are you concerned about

Answer 13

you might mess up postganglionic sympathetic fibers associated with that artery

can result in dryness of glands.

Question 14

Horner’s SYndrome

Answer 14

damage to the cervical sympathetic trunk
SLIGHT ptosis of the upper lid, due to paralysis of tarsal muscle
pupillary constriction
anhidrosis and blushing

Question 15

Slight ptosis vs complete ptosis

Answer 15

horner’s syndrome vs CN III lesion

Question 16

Dorsal motor nucleus of X sens out what kind of fibers to where

Answer 16

preganglionic parasympathetic fibers
to scattered ganglia in pharynx, larynx, thorax, and abdomen

=the parasympathetic nucleus for thorax and abdomen=BIG TERRITORY
