Study Notes
Nociceptive Pain
- Nociceptive pain is a process involving the transduction, transmission, perception, and modulation of impulses from nociceptors.
- Nociceptors are activated by stimuli following tissue damage (cuts, burns, tumors, chemicals).
- These stimuli trigger the nociceptors to send signals to the nervous system.
Neuropathic Pain
- Neuropathic pain originates from changes in the peripheral or central nervous system.
- Peripheral nervous system changes contributing to neuropathic pain include peripheral sensitization, changes in ion channels, and neuroplasticity.
- Neuroplasticity describes abnormal reorganization of nerve endings after damage.
- Central nervous system changes involve increased excitability of central neurons, altered neurotransmitter release and binding, and nerve reorganization following injury.
- These changes alter and increase pain sensations.

Description
This quiz explores the mechanisms of nociceptive and neuropathic pain. Understanding how nociceptors function and the effects of neuroplasticity on pain perception are crucial. Test your knowledge on the processes that contribute to both types of pain and their underlying biological factors.
