A nociceptor ("pain receptor" from Latin nocere 'to harm or hurt') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals to the spinal cord and the brain. The brain creates the sensation of pain to direct attention to the body part, so the threat can be … Visa mer Nociceptors were discovered by Charles Scott Sherrington in 1906. In earlier centuries, scientists believed that animals were like mechanical devices that transformed the energy of sensory stimuli into motor … Visa mer In mammals, nociceptors are found in any area of the body that can sense noxious stimuli. External nociceptors are found in tissue such as the skin (cutaneous nociceptors), the corneas, and the mucosa. Internal nociceptors are found in a variety of organs, such as the Visa mer Ascending Afferent nociceptive fibers (those that send information to, rather than from the brain) travel back to the Visa mer Nociceptor neuron sensitivity is modulated by a large variety of mediators in the extracellular space. Peripheral sensitization represents a form of functional plasticity … Visa mer Nociceptors develop from neural-crest stem cells. The neural crest is responsible for a large part of early development in vertebrates. It is specifically responsible for development of … Visa mer The peripheral terminal of the mature nociceptor is where the noxious stimuli are detected and transduced into electrical energy. When the electrical energy reaches a threshold value, an action potential is induced and driven towards the central nervous system (CNS). … Visa mer Nociception has been documented in non-mammalian animals, including fish and a wide range of invertebrates, including leeches Visa mer WebbEach pain receptor forms one end of a nerve cell (neurone).
