Study Notes
Nociceptors and Pain Pathways
- Nociceptors are free nerve endings found in the skin
- Various stimuli activate ion channels present on nociceptor terminals, acting as molecular transducers
- Activation of these ion channels leads to depolarization of nociceptor neurons, initiating nociceptive impulses
- Nociceptive impulses then propagate along pain pathways
- Local anaesthetics, such as lidocaine, can block nociceptor activity
