1. This electric current creates action potentials within the connected afferent neurons . 2. The afferent neurons are either A fibers or C fibers. 3. The main function of the IHCs is to transmit sound information via afferent neurons . 4. These signals ( action potentials ) are transmitted along afferent neurons into the brain. 5. Often tumor cells secrete growth factors which activate receptors close to primary afferent neurons . 6. The primary afferent neurons responsible for histamine-induced itch are unmyelinated C-fibres. 7. In the spinal cord reflex pathway the afferent neuron transmits information to spinal cord interneurons. 8. The first order afferent neuron carries sensory information to the second order neuron in the dorsal horn. 9. In the spinal cord, however, at least 75 afferent neurons are required to produce firing. 10. Since bladder wall stretch is low during the storage phase, these afferent neurons fire at low frequencies.
