Nociceptor

A nociceptor is a sensory receptor that sends signals that cause the perception of pain in response to potentially damaging stimulus.

Nociceptors are the nerve endings responsible for nociception, one of the two types of persistent pain (the other, neuropathic pain, occurs when nerves in the central or peripheral nervous system are damaged).
