TPRV-1 mediates

Answer 2

hot peppers
pain for moderate ehat
pain from acidic environments

Question 3

nociceptor afferent nerves require

Answer 3

more stimulus energy

and are tonic receptors

Question 4

a delta fiebrs

Answer 4

large diameter with myelination and rapid conduction velocity
fast or first pain
inhibition of C fibers

Question 5

Adelta HTM fibers synapse on

Answer 5

secondary nerves

small diameter and no myelination
slow conduction velocity
70% of all pain fibers

Question 7

c fibers stimulated by

Answer 7

thermal, mechanical, chemical stimuli

ischemia

Question 8

c fiber stimulation pain perception is

Answer 8

dull achy burning

Question 9

primary hyperalgesia is

Answer 9

increased pain responses at the site of the trauma

Question 10

hyperalgesia is enhanced by

Answer 10

inflammation

Question 11

inflammatory chemicals induce

vasodilation

Question 12

classic signs of inflammation

Answer 12

dolar, ruber, calor, tumor

Question 13

secondary hyperalgesia

Answer 13

released transmitters diffuse for some distance and stimulate pain nerve endings from nearby areas uninvolved with trauma

involves protein synthesis

Question 19

windup increases secondary nerve activating cascase that

Answer 19

induces early LPT

Question 20

allodynia

Answer 20

pain due to stimulus that doesnt normally provoke pain

inhibiting what cells blocks chronic pain

Answer 21

A11 cells that secrete dopamine

dysasthesias (abnormal sensations)

Question 23

CRPS I

Answer 23

reflex sympathetic distrophy

no obvious neural damage

Question 24

CRPS II

Answer 24

involves nerve injury

Question 25

within laminae of spinal cord

Answer 25

efferents go to laminae and release endorphins and enkephalins
