Neural receptors sensitive to stimuli that induce tissue damage; give rise to sensation of pain (nociception) and to autonomic reactions.

Sensory receptors that are preferentially sensitive to tissue trauma or a stimulus that would damage tissue if prolonged.

are those receptors which respond to damaging or potentially damaging stimuli e.g. hot and cold temperatures.

Nerve endings attached to peripheral nerves that sense tissue damage (or the threat of) by conveying heat, cold, or pressure.

are sense organs detecting damaging stimuli which are often perceived as being painful

specialized nerve endings that sense pain caused by injury such as pressure, swelling due to injury, heat, chemicals, etc.

The peripheral nerve organ or mechanism for the reception and transmission of painful or injurious stimuli.

Cutaneous and subcutaneous receptors (usually free nerve endings) specialized for the detection of harmful (noxious) stimuli

In animals, nerve endings that signal the sensation of pain. In humans, they are called pain receptors.

Nerve endings which detect and respond to painful or unpleasant stimuli.

(no-sih-SEP-turs). Nerve endings attached to peripheral nerves that detect potential or actual tissue damage. They sense unpleasant situations such as extreme heat, cold, a cut or pressure.

the endings of pain-sensitive nerves that, when stimulated by stress, muscular tension, dilated blood vessels, or other triggers, send messages up the nerve fibers to nerve cells in the brain, signaling that a part of the body hurts. (empty) paraesthesia parasthesia

specialized nerve receptor (neuron) that is stimulated by injury; a receptor for pain.
