2

3
Q
Nociceptive Pain
A
A nociceptor (pain receptor) is stimulated by a noxious or potentially damaging stimuli through mechanical, thermal or chemical means which is associated with inflammation
4
Q
What are the three types of nociceptive pain?
A
- mechanical
- thermal
- chemical

neuropathic pain
A
- pain initiated by a lesion or dysfunction of the somatosensory system, resulting in abnormal activity of the nociceptive pathway
- damage can result from drugs, disease, or trauma
6
Q
What nerve fibers are damaged in neuropathic pain?
A
primary afferent fibers. Ex. nerves that carry pain from hands to the spinal cord
7
Q
What nerve fibers are responsible for pain and temperature?
A
alpha-delta (small, myelinated) and C (small, unmyelinated)
8
Q
What never fibers are responsible for touch?
A
Alpha-beta - large, myelinated
9
Q
which nerve fibers are recruited last in the development in chronic pain?
