Nociceptor - Wikipedia
A nociceptor (from Latin nocere 'to harm or hurt'; lit. 'pain receptor') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1][2][3] to the spinal cord and the brain.
What Are Nociceptors? - Verywell Health
Jun 6, 2023 · Nociceptors often referred to as your "pain receptors," are free nerve endings located all over the body, including the skin, muscles, joints, bones, and internal organs. They play a pivotal role in how you feel and react to pain.
Physiology, Nociceptive Pathways - StatPearls - NCBI Bookshelf
Sep 26, 2022 · Nociception refers to the central nervous system (CNS) and peripheral nervous system (PNS) processing of noxious stimuli, such as tissue injury and temperature extremes, which activate nociceptors and their pathways. Pain is the subjective experience one feels as a result of the activation of these pathways.
Nociception - Wikipedia
Potentially damaging mechanical, thermal, and chemical stimuli are detected by nerve endings called nociceptors, which are found in the skin, on internal surfaces such as the periosteum, joint surfaces, and in some internal organs.
Physiology, Nociception - StatPearls - NCBI Bookshelf
May 1, 2023 · Nociception provides a means of neural feedback that allows the central nervous system (CNS) to detect and avoid noxious and potentially damaging stimuli in both active and passive settings. [1] [2] [3] [4] [5] [6] The sensation of pain divides into four large types: acute pain, nociceptive pain, chronic pain, and neuropathic pain.
Nociceptor - an overview | ScienceDirect Topics
A nociceptor is a type of receptor that signals potentially harmful stimuli in the tissue, categorized into mechanoreceptors, mechanical/thermal receptors, and polymodal receptors responsive to various stimuli.
Nociceptors - Neuroscience - NCBI Bookshelf
In short, there are three major classes of nociceptors in the skin: Aδ mechanosensitive nociceptors, Aδ mechanothermal nociceptors, and polymodal nociceptors, the latter being specifically associated with C fibers.
Studying human nociceptors: from fundamentals to clinic - PMC
Nociceptors remain an attractive therapeutic target: their sensitization makes an important contribution to many chronic pain states, they are located outside the blood–brain barrier, and they are relatively specific.

However, nociceptor activity does not per se lead to the perception of pain. The latter requires peripheral information to reach higher centers and normally depends on the frequency of action potentials in primary afferents, temporal summation of pre- …
Molecular mechanisms of nociception - Nature
Sep 13, 2001 · Nearly a century ago, Sherrington proposed the existence of the nociceptor, a primary sensory neuron that is activated by stimuli capable of causing tissue damage 1. According to this model,...
