Nociceptive pain (NP) - ANSWERS-o specialized nerve endings located in the
cutaneous and deep musculoskeletal tissue that detect painful stimuli from the
periphery and communicate this information to the CNS
o Nociceptors carry pain signal to the CNS by two primary sensory (afferent)
fibers: Aδ and C fibers
o NP starts outside of the nervous system from actual or potential tissue damage.
It has 4 phases.
Know the 4 phases of Nociception - ANSWERS-o Transduction
o Transmission
o Perception
o Modulation
Transduction - ANSWERS-noxious stimulus takes place in periphery
Transmission - ANSWERS-pain impulse moves from spinal cord to brain
Perception - ANSWERS-conscious awareness of painful sensation
Modulation - ANSWERS-inhibition of pain message
neuropathic pain (NEP) - ANSWERS-o results from an abnormal processing of the
pain message from an injury to nerve fibers
o Pain is described as: Constant dull ache, Burning, Stabbing, Electric shock,
Tingling
o Much more difficult to assess and treat
