Flashcards in Sensory Fx Deck (16):
1

conscious proprioception

the conscious awareness of body position and movement of body segments. It is regulated by the lemniscal system through pathways that begin in joint receptors and end in the parietal lobe of the cerebral cortex; it enables the cortex to refine voluntary movements.

2

agnosia (stereoagnosia)

inability to recognize what a sensation is despite relatively normal perception of the sensation. When it is tactile it is termed sterioagnosia (or asteriognosis). It would be the inability to determine the denomination of a coin despite normal ability to perceive it, for example.

3

graphesthesia

ability to identify letters or figures traced on the skin (without looking).

4

dermatone

is the area of skin supplied by a nerve root

5

sclerotome

is the area of bone and joints supplied by a single nerve root.

6

myotome

is the muscles supplied by a single nerve root

7

radiculopathy

damage to a nerve root (radiculitis is irritation). herniate disk damage

8

Myleopathy

is damage to the spinal cord from any cause.

9

Anesthesia/hypoesthesia

(or decrease) in sensation.

10

hyperpathia

exaggerated perception of normally painful stimuli.

11

hyperesthesia

excessive sensitivity to any modality. (decreased pain tolerance)

12

dysesthesia

perception of the pain when no stimulus is present.

13

paresthesia

is the detection of a sensation in the absence of any stimulus.

14

polyneuropathy

generalized damage to peripheral nerves.

15

double stimulation tests..

attention/neglect

16

suspended sensory loss

lesions at center of spinal cord with loss of pain and temperature sensation at several dermatones bilterally, with preserved sensation in lower body
