Many different types of stimuli
Where are nociceptors typically found?
In the skin
What is the purpose of ion channels on nociceptor terminals?
To transmit pain signals
What happens when local anaesthetics are applied to nociceptors?
They block pain impulses
What type of neurons are activated by various stimuli?
Nociceptors
What is the result of depolarization of nociceptor neurons?
Nociceptive impulses along pain pathways
Study Notes
Nociceptors
- Nociceptors are free nerve endings in the skin
- Nociceptor terminals contain ion channels that can be activated by various stimuli
- Activation of these ion channels acts as molecular transducers, depolarizing the neurons
- Depolarization of neurons triggers nociceptive impulses along the pain pathways
- Local anaesthetics, such as lidocaine, can block nociceptor activation
