What is neuropathic pain?

What is neuropathy?
A disturbance of function or pathological change in a nerve.
What is nociception?
The neural processes of encoding noxious stimuli
What is a nociceptive neuron?
A central or peripheral neuron of the somatosensory nervous system that is capable of encoding noxious stimuli.
What is nociceptive pain?
Pain that arises from actual or threatened damage to non-neural tissue and is due to the activation of nociceptors.
What is a nociceptive stimulus?
An actually or potentially tissue-damaging event transduced and encoded by nociceptors.
What is a nociceptor?
A high-threshold sensory receptor of the peripheral somatosensory nervous system that is capable of transducing and encoding noxious stimuli.
What is nociplastic pain?
Pain that arises from altered nociception despite not clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain.
What is a noxious stimulus?
A stimulus that is damaging or threatens damage to normal tissues.
What is pain threshold?
The minimum intensity of a stimulus that is perceived as painful.
