Q

describe transduction

A

-converts noxious stimuli to electrical impulses (noxious stimuli may be mechanical, thermal, or chemical and move from periphery (nociceptors) to doral horn of spinal cord)
-nociceptors are stimulated

Q

nociceptors are stimulated by the release of…

A

-histamine (excites nerve endings)
-lactic acid (builds up in tissue)
-bradykinin (vasodilator)
-prostaglandins (sends stimuli to CNS)
-substance P (sensitive recpetors on nerves for pain)
-serotinin (stimulates vasoconstriction)

Q

what are neuromodulators

A

-endogenous opiod compounds
-released by both pain and stress
-found in spinal cord and brain
-bind to specific opioid receptor sites and reduce perception of pain

Q

name two neuromodulators

Q

what is gate control theory

A

-provides ideas for pain relief emphasizing multiple dimensions of pain; relationship between pain and emotions (sensory, emotional, behavioral, cognitive)
-different pain interventions may be used to address various dimensions of pain for more holistic approach to therapy

basically says only certain signals can get through, motor is let through before sensory
