Pain patho Flashcards
nociceptive
neuropathic
cep: tissue, somatic or visceral
Near: nerve
nociceptive patho
site of injury
travels along spinal cord
brainstem
cerebrum
transduction: response to injury, generation of action potential
transmission: injury to spinal cord, cord to brain stem, stem to corrtex
perception: conscious experience: RAS
modulation: signals from brain travelling down
nociceptive patho
site of injury
travels along spinal cord
brainstem
cerebrum
gate theory
pain experience is dependent on the amount of info that get through to the brain
competition between pain and non pain fibres. eg. rubbing the area can distract.
somatic vs visceral pain feelings
neuropathic
som: well localised, achy, constant
visc: poorly localised, dull, referred
near: burning, tingling, shooting
Transduction
Transmission
Perception
Modulation
Transduction: response to injury. Generate action potential
Transmission: injury to spinal cord, then brain stem then cortex
Perception: conscious experience. RAS
Modulation: signals from brain travel down
