Autonomic Nervous System

Front 1

What is the restricted definition of the autonomic nervous system?

Back 1

That part of the peripheral nervous system which is motor to:
smooth muscle
cardiac muscle
glands

Front 2

What is the anatomical difference between the sympathetic and parasympathetic?

Back 2

Sympathetic ganglia are near the CNS, so PREganglionic fibers are SHORT, and POSTganglionic fibers are LONG.

Parasympathetic ganglia are near or in the target, so PREganglionic fibers are LONG, and POSTganglionic fibers are SHORT.

Front 3

What is the pharmacological difference between sympathetic and parasympathetic (neurotransmitters at postganglionic terminal)?

Back 3

sympathetic postganglionic terminal => norepinephrine

parasympathetic postganglionic terminal => acetylcholine

Front 4

Cell bodies of Sympathetic preganglionic neurons are found in ______

Back 4

The lateral intermediate gray of T1-L2

Front 5

The pathway of sympathetic motor fibers from the spinal cord to the sympathetic trunk is
1
2
3
4
5

Back 5

1 Lateral Intermediate Gray
2 Ventral Root
3 Spinal Nerve
4 White Communicating Ramus
5 Paravertebral Ganglion

Front 6

The Sympathetic Trunk spans _______________ of the vertebral column

Back 6

the entire length

Front 7

After entering the sympathetic trunk, a preganglionic nerve may:
1
2
3
4

Back 7

1 Synapse on a postganglionic neuron in the sympathetic trunk at the level of entry
2 ascend to synapse at a higher ganglion
3 descend to synapse at a lower ganglion
4 Exit as a splanchnic nerve to synapse at a Collateral ganglion

Front 8

Sympathetic Trunk outflow fibers may be:
1
2
3
4
5

Back 8

1 Preganglionic Splanchnic nerves
2 Postganglionic fibers following Gray Communicating Rami to reenter the spinal nerve
3 Direct Visceral Branches (C, upper T)
4 Superior Cervical Ganglion => carotid arteries => periarterial plexuses in head
5 Superior Cervical Ganglion => cranial nerves => target organ

Front 9

Gray Communicating Rami may be found _______
White Communicating Rami may be found _______

Back 9

The entire length of the spinal cord

T1-L2

Front 10

The cell bodies of Parasympathetic preganglionic neurons are in _______

Back 10

1 Brain stem nuclei of CN III, VII, IX, X

2 Lateral intermediate gray of S2,3,4

Front 11

Parasympathetic preganglionic neurons to the:
1 head and neck _____
2 thoracic and abdominal viscera ______
3 pelvic, perineal, abdominal organs ________

Back 11

1 CN III, VII, IX, X
2 CN X
3 S2,3,4 and their ventral rami

Front 12

The contents of the vertebral canal from superficial to deep are:

Back 12

vertebra =>
epidural space (fat, internal vertebral venous plexus)=>
dura mater =>
subdural space (potential) =>
arachnoid =>
subarachnoid (CSF, trabeculae) =>
pia mater (arteries and veins for spinal cord)
=> spinal cord

Front 13

Spinal cord and Vertebral column are the same length until ___________

Back 13

the 3rd fetal month

Front 14

At Birth, the spinal cord ends at ___________

Back 14

L2-3

Front 15

At 5 years of age through adulthood, the spinal cord ends at ____________

Back 15

L1-L2
