Answer 22

12

Question 23

What are the signals called that are going to the spinal cord or brain?

Answer 23

Afferent

A-Approch

Question 24

What are the signals called that are carried away from the CNS?

Answer 24

Efferent

E-Exit

Question 25

Peripheral Nervous System

Answer 25

Is divided into 2 sections: Somatic Autonomic

Question 26

Somatic

Answer 26

Relating to or affecting the body as distinguished from the mind. (Voluntary)

Question 27

Autonomic

Answer 27

Innervates with smooth muscle, cardiac muscles, and glands.

Question 28

Sympathetic

Answer 28

Fight or Flight

Question 29

Parasympathetic

Answer 29

Rest and Digest

Question 30

Brain

Answer 30

One of the largest organs in the body

Question 31

Signals or nerve impulses that follow specific one-way routes to and from the CNS are called?

Answer 31

Neuronal Pathways

Question 32

What is the role of the Muscle Spindle?

Answer 32

Measure muscle length

Question 33

What is the role of the Golgi Tendon Organs?

Answer 33

Measure muscle tension

Question 34

What is the role of the Joint Kinesthetic receptors?

Answer 34

Joint position and movement

Question 35

Receptors that detect many different types of stimuli both within the body and outside the body

Answer 35

Sensory function

Question 36

Integrates sensory information by analyzing and storing and by making decisions for appropriate responses.

Answer 36

Integrative functions

Question 37

Muscular contraction or glandular secretion. Motor neurons carry information AWAY from the brain towards the spinal cord. (Efferent)

Answer 37

Motor Function

Question 38

Gate Control Theory

Answer 38

1. Pain signals travel to the CNS slower then Somatic sensations. 2. Therefore, touch impulses reach the spinal cord before the pain impulses. 3. The faster the touch impulses can then block the pain impulses thus decreasing the sensation of pain.

Question 39

Clinical connection of Nervous System

Answer 39

1. Massage enhances the development and growth of nervous tissue especially in newborn children. 2. Massage increases the production and release of a number of neurotransmitters and other substances from the nervous tissue that facilitate homeostasis.

Question 40

Nervous System Comparison

Answer 40

1. Communicates by means of electrical impulses 2. Reacts quickly to stimuli. 3. Has relatively local and specific effects on target organs 4. Adapts quickly to continual stimuli
