0

This is the SENSORY component that enters the dorsal root of the spinal nerves of the SOMATIC NS

Afferent

1

This is the MOTOR component of the AUTONOMIC NS under the influence of the hypothalamus.

Efferent

2

The SYMPATHETIC NS place of exit from the CNS

THORAX and LUMBAR regions of the spine (thoracolumbar NS)

3

The function of the SYMPATHETIC NS

Mobilization of bodily resources "FIGHT OR FLIGHT".

4

In the VISCERAL NS The POSTganglionic FIBER secretes ____________.

Norepinephrine (NE)

5

TRUE or FALSE: in the VISCERAL NS the POSTganglionic fiber is relatively short.

FALSE, the POSTganglionic fiber is relatively LONG in the VISCERAL NS

6

In the VISCERAL NS the PREganglionic fiber secretes _________.

Acetylcholine (ACH)

7

TRUE or FALSE: in the VISCERAL NS the PREganglionic fiber is relatively short.

TRUE, the PREganglionic fiber is relatively SHORT in the VISCERAL NS

8

This is composed of 22 sympathetic ganglia

Sympathetic Chain

9

Axons of MYELINATED PREganglionic FIBER from where they leave the ventral root to where they enter the sympathetic chain.

White Ramus

10

Axons of NON-MYELINATED POSTganglionic Fiber from sympathetic chain to ventral root.

Gray Ramus

11

Places of exit from CNS are the brain and the sacral region of the spine (CRANIOSACRAL) and its functions are to conserve and store bodily resources (active after eating).

Parasympathetic NS

12

In the parasympathetic NS, the preganglionic fiber;

1. Enter/Exit from: _________________
2. Size: _________________
3. Secretes _________________

1. From Brain/spine to Collateral ganglion
2. Long
3. Acetylcholine (ACH)

13

In the parasympathetic NS, the postganglionic;

1. Enter/Exit from: _________________
2. Size: _________________
3. Secretes _________________

1. From Collateral ganglion to organ
2. Short
3. Acetylcholine (ACH)

14

This is where fibers cross from one side of the spinal cord to the other.

Gray Commissure

15

These are found in the lateral area of white matter and consist of short tracts that connect to different levels of the spinal cord.

Ground Bundles

16

This tract originates in the spinal cord and terminates in the thalamus.

Spinothalamic Tract

17

This tract originates in the cortex and terminates in the spinal cord.

Corticospinal Tract

18

These columns are found between dorsal horn and dorsal fissure (SENSORY and AFFERENT).

Dorsal Columns

19

These columns are found between dorsal horn and ventral horn (SENSORY and MOTOR).

Lateral Columns

20

These columns are found between the ventral horn and ventral fissure.

Ventral Column

21

NS classification meaning TOWARD the HEAD.

Rostral

22

NS classification meaning TOWARD the TAIL.

Caudal

23

NS classification meaning ABOVE a structure.

Superior

24

NS classification meaning BELOW a structure.

Inferior

25

NS classification meaning TOWARD the MIDLINE.

Medial or Proximal

26

NS classification meaning AWAY from the MIDLINE.

Lateral or Distal

27

NS classification meaning FRONT.

Anterior

28

NS classification meaning BACK.

Posterior

29

This is the FRONT BASE of the brain.

Vental

30

This is the BACK TOP of the brain.

Dorsal

31
