-
primary hyperalgesia
increase of magnitude and duration of response
-
secondary hyperalgesia
enlaring of receptor fields of nerves
-
allodynia
pain occurring in response to stimuli that doesn't normally cause pain
-
transduction
when pain receptors convert pain stimulus into electrical activity
-
this fiber is not blocked by opiods
a delta
-
a delta properties
- small myelinated
- respond to intense mechanical stimulation and heat or cold
- sharp, stabbing, pricking
-
this fiber is blocked by opiods
c fibers
-
c fiber properties
- small or unmyelinated
- dull, throbbing, aching, burning, tingling, or tapping
- slow onset
- long lasting
- diffusely localized
- accompanied by sweating, increase HR and BP
- nausea
-
this fiber is non painful, related to vibration, stretching, and mechanical pressure, can be involved in abnormal prolonged pain perception
a beta
-
this can trigger reflex muscle spasms and are subject to "pain gaiting"
interneurons
-
SC pain transmission is dorsal or anterior horn involved
dorsal
-
where does conscious perception of pain emerge?
cortex
-
gate control theory
pain severity determined by the balance of excitatory and inhibitory inputs in the SC
-
nocicpetive pain
clear stimulus response
-
neuropathic pain
- usually acommpanied by SnS of neurological dysfxn
- ie paresthesias, itching, anesthesia, weakness
-
dysfxnal pain
pain that doesn't serve a protective fxn
-
nociceptors
nerve endings contributing to pain sensation
-
peripherial sensation
process of releasing chemicals that increase response of nociceptors to noxious stimuli
-
central sensitization
CNS adapts nociceptive input and increase magnitude and duration of response to the noxious stimuli
