Flashcards in Physiology of Pain (MC) Deck (17):
1

Pain is classified by

disease, anatomy, general location, duration, intensity

2

Physiologic pain

nociception = potential tissue damage, NOT conscious

3

Pathologic pain = clinical pain

tissue damage

4

first pain fiber

Ag fiber (sharp and pricking)

5

second pain fiber

C fiber (burning, aching pain, signals inflamed tissues)

6

not activated by tissue-damaging event, activated by inflammation, very sensitive to mechanical stimulus

silent or sleepingimportant in the development of primary hyperalgesia

7

Transduction: inflammatory pain → ___

peripheral sensitization

8

where does transduction occur

at the site of injujry

9

increase of response to a noxious stimulus at injury

Primary hyperalgesia

10

pain response to non-noxious stimuli

Allodynia

11

repetitive stimuli leads to central sensitization

Modulation

12

Modulation leads to ______

increased excitability of peripheral neurons

13

an increase of response to a noxious stimulus adjacent to injury.

Secondary hyperalgesia

14

Modulation mediated by

mediated by dorsal horn neurons (CNS)-mediated by activation of the NMDA receptor

15

interacting with animal, observing animal

DIVAS = dynamic interactive visual analogic Scale

16

developed for dogs with osteoarthritis

Helsinki Chronic Pain Index

17
