Morphology

nociceptor = noci + cept + or

This is a technical term built from classical elements meaning roughly 'pain/harm' + 'receive' + '-or', but the full meaning is not transparent to an average B1 learner.

Etymology

Nociceptor comes from the Latin nocere, meaning 'to hurt', and the part -ceptor, which is like the English word 'receive' and means 'to take in'. So a nociceptor is a 'receiver' of hurt, which is why it is a nerve cell that senses pain.
