Flashcards in Sensory Exam Deck (31):
1

if the primary sensory modality isn't in working order the deficit is referred to as

anesthesia and analgesia

2

the PNS or afferent organ have their cell bodies here

dorsal root ganglia

3

in the spinal cord, the sensory pathway/mechanosensory ascends on this side (contralateral, ipsilateral)

ipsilateral

4

the sensory pathway synapses here in the upper extremity

cuneate nucleus (cuneatus tract)

5

the sensory pathway synapses here in the lower extremity

gracile nucleus (gracilis tract)

6

in the spinal cord, the name of the area that houses the sensory/mechanosensory pathway

dorsal columns

7

in the spinal cord, the sensory pathway of pain/temperature ascends on this side (ipsilateral, contralateral)

contralateral

8

in the spinal cord, the name of the area that houses the pain/temperature pathway

spinothalamic tract

9

posterior aspect of the shoulders is this nerve root

C4

10

lateral aspect of the upper arms is this nerve root

C5

11

medial aspect of the lower arms is this nerve root

T1

12

tip of the thumb is this nerve root

C6

13

tip of the middle finger is this nerve root

C7

14

tip of the pinky finger is this nerve root

C8

15

3 ways to test superficial sensory

pain, temperature, light touch

16

tactile disc of merkle deals with this sensation

light touch

17

neuro-pathway for light touch

anterior spinothalamic tract

18

deficits to light touch in dermatomal pattern may indicate

nerve root compression or peripheral nerve lesions

19

neuro-pathway for pain

lateral spinothalamic tract

20

deficits in pain in dermatomal pattern may indicate

nerve root compression or peripheral nerve lesions

21

analgesia means

areas insensitive to pain

22

hypalgesia means

decreased sensation

23

hyperalgesia means

increased sensitivity

24

loss of vibration

pallanathesia

25

tract that vibration is carried in for upper extremity

cuneatus

26

tract that vibration is carried in for lower extremity

gracilis

27

temperature is carried along the same pathway as:

pain

28

compression of dorsal nerve root usually has these sensations

numbness and tingling, loss of vibration

29

compression of this area could cause hyporeflexia with no muscle atrophy

dorsal nerve root

30

compression of this area causes muscle weakness and loss of reflexes

anterior (motor) nerve root

31

causes of compression

disc herniation, DJD, trauma, inflammation, tumors
