Q

1) 3 Components of the Nervous System?

2) Which component has 2 subcategories

A

1) Central vs. Peripheral vs. Autonomics

2) Autonomics = Parasympathetic vs. Sympathetic

2
Q

Which nervous system component does the following:

A-DILATES pupil
B- Stops Saliva secretion

C-Constricts Bronchi
D- Converts glycogen —>Glucose
E-STOPS Bladder Contractions

F- Releases Bile

G- Erection, Relaxes Uterus

H- Constricts coronary vessels

i = systemic/ peripheral blood vessel diameter

J= INC renin secretion

A

-Both Autonomic Children-

A-SYMPATHETIC
B-SYMPATHETIC

C-ParaSympathetic

D-SYMPATHETIC
E- SYMPATHETIC

F- ParaSympathetic

G- ParaSympathetic

H- ParaSympathetic

i= SYMPATHETIC

J= SYMPATHETIC

3
Q

1) Sympathetic NS origins from which spinal segments exactly?
2) what about ParaSympathetic NS? [2]

A

1) Sympathetic Preganglionic Neurons are in T1-L2 [IML lateral horns] of spinal cord gray matter
2) ParaSYmpathetic Preganglionic Neurons start from Cranial nerves (3,7,9,10) OR Spinal segments S2 –> S4

4
Q

1) Preganglionic fibers from SYMPATHETIC NS leave spinal cord thru the ____ rami (____) and then housed in the ___ _____, enter the ____ _____
2) Where are Ganglionic neurons located for each system? [2]
3) What is the passage for SYMPATHETIC POSTganglionic fibers
4) SYMPATHETIC Preganglionic fibers are ____& ______ hile
5) What does WIGO mean?

A

2) Ganglionic neurons =
ºWITHIN [SCGT] OR collateral ganglion outside [SCGT] = SYMPATHETIC /////
ºPeripheral ganglia=PARAsympathetic
————————————————————————————
3) POSTganglionic fibers leave sympathetic trunk thru GRAY RAMI (as Gray communicating ramus) & pass thru spinal nerve again b4 actually terminating in organ
———————————————————————————–
4) SYMPATHETIC Preganglionic fibers are SHORT & myelinated

5) WIGO = White in (PreG in to SCGT) and Gray Out (PostG out of SCGT)

5
Q

A: [T or F] Sympathetic NS Preganglionic fibers can DIRECTLY simulate epi/NorEpi from Adrenal Medulla

B: Sympathetic division is responsible for the _____ ____ tone

C: [T or F] Sympathetic PREganglionic fibers tend to ascend or descend within the [Sympathetic Chain Ganglion Trunk] b4 actually synapsing

A

A: TRUE!

B: Sympathetic division is responsible for [Vasomotor sympathetic tone]

C: TRUE!

6
Q

1) Which ganglia does the PREganglionc neurons of the PARAsympathetic NS synapse with? How does this effect the length of these fibers?
2) Are these fibers myelinated or nah?
3) Which 3 Ganglion does VAGUS CN10 travel to?

A

1) Peripheral ganglia located NEAR target organ [WHich is Why these PREganglionc PARAsympathetic fibers are so long]
2) PreGanglionic for BOTH systems are Myelinated
3) Thoracic, Abdominal & Cardiac ganglia

7
Q

B: Why should you find NO white rami below L2?

A

—SYMPATHETIC NS

B: Sympathetic input from spinal cord stops at L2 = no white rami below that—> only chain and gray rami

8
Q

What are the Splanchnic Nerves? [3]

A

STRANGE Group of Nerves found in Thoracic [T5-T10], Sacral and Pelvic regions.

  1. Thoracic Splanchnic= Sympathetic NS BUT have PARASympathetic qualities (don’t synapse at SCGT & have LONG PREganglionic n.)

º[Sacral Splanchnics also=Sympathetic]

  1. Pelvic Splanchnic= PARASympathetic NS
9
Q

1: Which “road map guidance” does the Sympathetic fibers use to get to their targets?
2: What is the ganglion impar?

A

1: Sympathetic fibers follow Blood Vessels & peripheral nerves to their targets
2: Gang impar= The only randomly detached unpaired ganglion

10
Q

1) Where is the Celiac Ganglion located in the body? [3]

2) Is this ganglion Sympathetic or PARAsympathetic?

A

1) INSIDE DIAPHRAGM, In front of T12 Vertebrae & under the heart
2) MOSTLY SYMPATHETIC (from grtr and lesser splanchnic n.)

11
Q

A: Because there is no ___ ____ in the cervical cord, how do SYMPATHETIC preganglionic fibers get to the face?

B: What functions do they do in the face? [3]

A

A: Since no LATERAL HORN (IML) in cervical cord sympathetic preganglionics ascend from thoracic cord to synapse in Superior/Middle/Inferior cervical chain ganglia

B: Dilator Pupillae, Eyelid Tarsal muscle, Facial sweating

Tarsal HELPS [levator palpebrae superioris] elevate eyelid

12
Q

1- What is Horner’s Syndrome caused by?

2-Name the 4 Major sx and what they mean

3-What cancerous tumor is known for causing Horner’s Syndrome?

A

2-
A: Ptosis=Drooping Eyelid

B: Miosis= Constricted pupil

C: Anhidrosis = Inability to Sweat

D: Flushed Red Skin

  1. PANCOAST TUMOR = Apex Lung tumor pressing Against inferior cervical sympathetic ganglion
13
Q

1) Which Central Nervous System , Rounds UP the lens and constricts the pupil?
2) POSTganglionic fibers from Sympathetic [______] releases ____ @ target organs…. while PARAsympathetic releases ______

A

1) PARASYMPATHETIC NS

2) POSTganglionic fibers from Sympathetic[Adrenergic] releases NE/Epi …..
while PARAsympathetic[Cholinergic] releases Acetylcholine

14
Q

1) Which nerve is responsible for relaying Lacrimal Gland SENSATION? Give an example
2) What n. induces TEARS for Lacrimal Gland? What does this nerve run with to get there?

A

1) [Trigeminal/CN5B1^Opthalmic»Lacrimal n.] Relays SENSATION for Lacrimal Gland (ex. being stabbed in eye with hot comb)
