2. Afferent and efferent tracts

3. Inner core of gray matter and superficial white mater

12

What is gray matter?

1 consists of UNMYELINATED neurons

2. Contains capillaries, glial Cells, cell bodies, and dendrites

13

What is white matter?

31 pairs of spinal nerves

-8 cervical
-12 thoracic
-5 lumbar
-5 sacral
-1 coccygeal

16

In the PNS, bundles of nerve fibers + axons are supported by _________ fibers and conductor information to the ________.

1. Connective fibers

2. CNS

17

T or F: PNS nerves although encased in fibrous sheaths, are relatively unprotected.

True

18

How many roots do spinal nerves have?

2. (Anterior and a posterior root)

19

What does the anterior root carry?

Anterior roots carry MOTOR information AWAY from the CNS (efferent fibers)

20

What does a posterior root carry?

Carries information regarding SENSATION to the CNS (afferent fibers)

21

What are ganglia?

Clusters or swellings of cells that give rise to the peripheral and central nerve fibers

22

What are ganglia divided into?

Sensory ganglia and autonomic ganglia

23

What are the two subcategories of the ANS?

1. Sympathetic Nervous system

2. Parasympathetic Nervous System

24

What does the sympathetic division do?

Prepares the body for emergency response; generally stimulating response

25

What is another name for the sympathetic nervous system and what neurotransmitter is released?

Flight or Fight

Neuroepinephrine

26

What is the responsibility of the parasympathetic nervous system?

Conserving and restoring energy; generally inhibitory response

27

What is another name for the parasympathetic nervous system and what neurotransmitter is released?

Rest + digest; Acetylcholine

28

T or F: The ANS automatically contains portions of the CNS + PNS

True

29

What is the ANS concerned with?

Concerned with innervation for involuntary processes, glands, internal organs, and smooth muscle

30

The emphasis of the ANS is?

Homeostasis and a person’s response to stress
