MOTOR SYSTEM

Question 1

based on?

Answer 1

power, tone, bulk

Question 2

power scale?

grouped as?***

Answer 2

0-5
0-no movement
1-spontaneous twitch
2-movement with gravity eliminated
3-movement against gravity but not against resistance
4-movement against gravity and some resistance
5-normal

***upper and lower extremities

Question 3

resistance of a muscle to passive movement indicates whether a lesion is in the CNS?

Answer 3

tone

Question 4

decreased bulk may indicate a lower motor neuron process, a myopathy, or disuse and is most easily noted with asymmetric?

Answer 4

bulk

Question 5

sensation based on?

Answer 5

light touch
pain/temp
vibration/joint position
cortical sensory

Question 6

this sensation is mediated by both the posterior column and spinothalamic sensory tracts?

Answer 6

light touch

Question 7

this sensation tests mostly spinothalamic fxn; it is tested with a safety pin and warm or cold pack

Answer 7

pain/temp

Question 8

sensations are both posterior column functions. Tested with tuning fork

Answer 8

vibration/joint position

Question 9

modalities require cortical input in addition to the sensory modalities noted above.

Absence or asymmetry of these modalities may indicate cortical disease

Answer 9

cortical sensory

Question 10

ability to recognize an object by its 3-D shape only

Answer 10

stereognosis

Question 11

ability to recognize a letter or number traced in the hand

Answer 11

graphesthesia
