A afferent fibres have average fibre diameter 2-5mm and conductive velocity 5-30 m/s. Nociceptors in intervertebral discs are normally limited to the outer third of the annulus, could be the substrate for discogenic pain when they are expanded over the larger annular area and penetrate further into the degenerated disk along the vasculature and ssures. They occur in erosion channels extending from the subchondral bone to the articular cartilage.A human study by (Kiter et al., 2010)[14] showed both free and encapsulated nerve endings in the human iliolumbar ligament.

The second type is C fiber axons, which are not surrounded by myelin, and thus transmit action potentials at a slower speed., Due to the difference in transmission speed between the A and C fibers, the pain signals from the A fibers reach the spinal cord first. Binocular vision is an adaptation found in many animals that benefit from good depth perception.

PMID 18583048, Basbaum AI, Jessell T. The Perception of Pain. Thus, a noxious stimulus can be categorised into one of these three groups. 2) The sensory receptors, neurons and pathways make up the _____ division of the nervous system. polysynaptic reflex. $$. The peripheral end of the axon contains encapsulated proteins called transduction proteins (TRP), which can be activated by a specic stimulus.

The division of the PNS that controls smooth muscle, glands, and other non-voluntary effectors is the _________ nervous system. The nociceptors can also detect chemical and thermal damage. e. light. Which of the following cranial nerves conveys taste and general sensation from the posterior third of the tongue? Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs).

The apparent lack of a response to a noxious stimulus may result because of different receptors located on the membrane of the end terminal (free nerve ending) or the stimulus intensity is insufficient. The EAA, particularly glutamate, produce the initial excitatory response on the postsynaptic, second-order, neuron, followed by the release of peptides, including substance P, causing a more prolonged depolarization and sustained nociceptive transmission.
