Sherrington used many different … 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 … Visa mer Ascending Afferent nociceptive fibers (those that send information to, rather than from the brain) travel back to the 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 The peripheral terminal of the mature nociceptor is where the noxious stimuli are detected and transduced into electrical energy.
