WebFigure 13.1.1 – Receptor Classification by Cell Type: Receptor cell types can be classified on the basis of their structure. Sensory neurons can have either (a) free nerve endings or … 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 … Ver mais 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 … Ver mais In mammals, nociceptors are found in any area of the body that can sense noxious stimuli. External nociceptors are found in tissue such … Ver mais 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 … Ver mais Nociceptor neuron sensitivity is modulated by a large variety of mediators in the extracellular space. Peripheral sensitization represents a form of functional plasticity … Ver mais Nociceptors develop from neural-crest stem cells. The neural crest is responsible for a large part of early development in vertebrates. It is … Ver mais Ascending Afferent nociceptive fibers (those that send information to, rather than from the brain) travel back to the spinal cord where they form synapses in its Ver mais Nociception has been documented in non-mammalian animals, including fish and a wide range of invertebrates, including leeches, nematode worms, sea slugs, and larval fruit flies.
