Enkephalin functions by binding opioid receptors to cause inhibition of the post-synaptic neuron, thus inhibiting pain. The periaqueductal grey also contains opioid receptors which explains one of the mechanisms by which opioids such as morphine and diacetylmorphine exhibit an analgesic effect. Visa mer 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 … 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 the peripheral nervous system (PNS). The neural-crest stem cells split from the neural … Visa mer 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 dorsal horn. This nociceptive fiber (located in the periphery) is a first order … 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 … 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), … 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 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 Webb18 okt. 2008 · All receptors have the capacity to adapt.
