Answer 0

Neurons (cell bodies) in the cns

Question 1

Nerve

Answer 1

Bundle of many axons in the pns

Question 2

Nerve description

Answer 2

Grouped together and coated in myelin (like insulation)

Question 3

Nerves Innervate

Answer 3

Muscle by conducting messages from the cns to muscle fibers, leaving (efferent)

Question 4

Nerves convey

Answer 4

Sensory input from muscles back to the brain, incoming (afferent)

Question 5

Types of nerves in the pns

Answer 5

Spinal and cranial

Question 6

Spinal nerves

Answer 6

Convey motor input to the body
Convey sensory input from the body- both outgoing and incoming fibers
Emerge from brainstem

Question 7

Cranial nerves

Answer 7

Convey motor input to head, mouth, articulators, and some internal organs
Convey sensory input from head, mouth, articulators, and some internal organs–>some only motor or sensory or both
Merge form brainstem

Question 8

Answer 8

Spinal cord

Question 9

Answer 9

Brainstem

Question 10

In the cns. A bundle if axons coated in myelin is called

Answer 10

A tract

Question 11

Ganglia description

Answer 11

Collection/group of neurons(nerve cell bodies) outside the cns
Found in the pns (not cns)

Question 12

Ganglia continued

Answer 12

Which person certain function, outside the cns
Gray mater
Exception is basal ganglia in cns

Question 13

In te cns a group of neurons is called a

Answer 13

Nuclei

Question 14

Spinal, cranial nerves and ganglia of the pns have various functions

Answer 14

Serve as a connecting system between cns and body

Engage/provide voluntary and involuntary control over the body

Question 15

Spinal, cranial, and ganglia uses a two way communication system

Answer 15

Motor-efferent- bruins sending info from cns to body

Sensory (afferent) neurons sending info to the cns from the body

Question 16

Pns has two major divisions and types of control

Answer 16

Somatic- voluntary

Autonomic - involuntary control

Question 17

Nerve receive impulse from cns successfully synapse and shoot impulse into

Answer 17

Pns (voluntary and involuntary)

Question 18

Humans nervous system break down to

Answer 18

Cns( Brain, spinal cord)

Pns(cranial and spinal nerves and ganglia)

Question 19

Pns breakdown to

Answer 19

Somatic(voluntary)

Autonomic (involuntary)

Question 20

Answer 20

Control of skeletal muscle

Reflex arc

Question 21

Autonomic breakdown to

Answer 21

Enteric- digestion
Sympathetic- fight/flight
