Rest & Digest

A

Parasympathetic

23
Q

____ axons are eveywhere, superficial & deep

A

Sympathetic

24
Q

Sympathetic divison axons arise from?

A

Thoracolumbar spinal cord T1-L2

25
Q

appear as small lateral horns of the H-shaped gray matter
Consists of the cell bodies of the presynaptic neurons of the sympathetic nervous system.

A

Intermediolateral cell column

26
Q

Runs from the base of the skull to the tip of the coccyx

A

Sympathetic Chain (trunk, Blue)

27
Q

Little globs on chain where synapses occurs

A

Sympathetic chain ganglia

28
Q

Myelinated axons, only present at spinal cord levels T1 through L2

Where signal enters into the ganglia from nerve root

A

White rami (pink)

29
Q

Contains unmyelinated axons, present at ALL 31 SPINAL CORD LEVELS

Where signals leave ganglia to exit out of spinal nerves to rest of body

A

Gray Rami (red)

30
Q

3 pathways of sympathetic?

A
  1. TO body wall (only from T1-L2)
  2. TO viscera above diaphragm (T1-T4)
  3. To viscera below diaphragm (T5-L2)
31
Q

Nerves that are formed by signals coming off sympathetic chain in pathway to viscera below diaphragm

A

Splanhneic nerves

32
Q

What must start at T5-L2?

A

Sympatheic signals to the viscera below the diaphragm 

33
Q

Only go to deep structures (not genitals)

A

Parasympathetic

34
Q

_____ nerve, to cilliarly ganglion (synapse) -> post ganglionic-> lacrimal gland (eye)

A

C3 Occulomotor

35
Q

______ nerve to PPG (synapse) -> post ganglionic -> pupillary constriction

OR Submandibular ganglion (synapses) -> post ganglionic -> Salivary glands

A

C7 Facial Nerve

36
Q

___ nerve to Otic ganglion (synapse) -> post ganglionic -> parotid glad

A

C9 Glossophryngeal nerve

37
Q

___ nerve to (no specific ganglion associated) synapse on body wall, down to thorax:
-Heart
-Thorax
-part of digestive system

A

C10 Vagus Nerve

38
Q

Carnial nerves para?

A

C3, C7, C9, C10

39
Q

Sacral nerves para?

A

S2-S4

40
Q

In the sacral pathway (Para) there are IML like regions in the sacral region of spinal cord arise is what area

A

Lateral areas

41
Q

____ arise from he same cord levels of GVEs

A

GVAs

42
Q

Pain in viscera feels like pain somewhere else (somatic areas)

A

Referred Pain

43
Q

___ enter the SAME spinal cord levels as GVAs

A

GSA

44
Q

Pain in appendix
Send signal via visceral sensory nerve
Enter via DORSAL root ganglion .
Send signal from respective somatic sensory nerve
Enter via dorsal root
BOTH _____ together

A

Synapse together= pain referred to somatic region instead of visceral!

Pain on side.
