1

consists of the nerves that branch out from the CNS and connect it to the other body parts

peripheral nervous system

2

the division in the ANS that responds using a fight or flight response when there is a perceived or actual threat to survival

sympathetic nervous system

3

the division of the ANS that works to conserve body energy and is partly responsible for slowing heart rate, digesting food, and eliminating body wastes

parasympathetic nervous system

4

which cranial nerves are sensory?

Cranial nerves I, II, VIII

5

Which cranial nerves are motor?

Cranial nerves III, IV, VI, XI and XII

6

cortex; responsible for movement; motor and sensory neurons; consists of two hemispheres
Pyramidal and extrapyramidal motor pathways

cerebrum

7

controls and coordinates muscle movements

cerebellum

8

respirations, heartbeat, vasomotor activity
Midbrain, pons, medulla oblongata

brain stem

9

transmits motor impulse from the brain to the spinal cord and sensory impulses from the peripheral sensory neurons to the brain

medulla oblongata

10

the largest part of the brain

Divided into two hemispheres

Governs thought and learning

cerebrum

11

Second largest part of the brain
Functions:
Involuntary movement
Coordination
Muscle tone
Balance
Equilibrium (semicircular canals)

cerebellum

12

Coordinates the action of voluntary muscles and adjusts to impulses from proprioceptors within muscles, joints, and sense organs

cerebellum

13

Manufactures and absorbs cerebrospinal fluid (CSF)

ventricles

14

functions of CSF

Protects structures
Maintains constant intracranial pressure

15

Functions:
Provides centers for reflex action
Pathway for impulses to and from the brain

spinal cord

16

regulates the expenditure of energy and secretes epinephrine and norepinephrine.

Autonomic nervous system

17

*evaluate body posture
*cranial nerve-assessment technique
*motor function
*gait movement and balance; Romberg test

mini-mental staus examination

18

not opening eyes,
not obeying commands
not uttering understandable word

coma

19

Assessment tool for evaluating LOC ( Level Of Consciousness)

Glasgow Coma Scale

20

What is a normal response on a Glasgow coma scale?

15

21

What score on a Glasgow coma scale is considered coma?

score of 7 or less

22

What are the impaired cerebral functions of the nervous system?

*decorticate posturing
*decerebrate posturing
*flaccidity

23

position in which the arms are flexed, the fists clenched, and the legs extended following neurologic trauma

decorticate posturing

24

position in which the extremities are stiff and rigid following neurologic trauma

decerebrate posturing

25

lack of motor response to stimuli

flaccidity

26

Patient responds immediately, fully, & appropriately to visual, auditory, & other stimulations

Conscious

27

Patient is drowsy at inappropriate times, but can be aroused, only to fall asleep again. Responses are delayed. Speech is incoherent. Response to painful stimuli

somnolent

28

Patient is aroused only by vigorous and repetitive physical, auditory, or visual stimulation. Patient has one or two word answers.

stuporous

29

Patient is unresponsive except to superficial, relatively mild painful stimuli to which the patient makes some purposeful motor responses (movement) avoid further stimulation.

semi comatose

30

-Patient has no spontaneous movement and respiratory rate is irregular

comatose
