Autonomic information is regulated by the______ at the presynaptic neurons

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

1

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

T1

2

Describe how sympathetics get into the head

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

3

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

whaever that ganglion is, that's where post sympathetic gets distributed,
that ganglion takes care of tis "territory"

4

Cervical ganglion that is always present

superior cervical ganglion

5

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

posterior
embedded in or deep to

6

The superior cervical ganglion's distribution is

sympathetics to the head.

7

Superior cervical ganglion sends off _____ nerve and _____plexus

internal carotid N
internal carotid plexus

8

all ganglia give off

perivascular plexuses

9

Branches from the internal carotid plexus (4)

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

10

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

perivascular plexuses

11

Deep petrosal nerve joins_________ nerve to form_______nerve

greater petrosal nerve
vidian nerve

12

Vidian nerve innervates

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

13

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

you might mess up postganglionic sympathetic fibers associated with that artery

can result in dryness of glands.

14

Horner's SYndrome

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

15

Slight ptosis vs complete ptosis

horner's syndrome vs CN III lesion

16

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

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

=the parasympathetic nucleus for thorax and abdomen=BIG TERRITORY
