Question

Ectopic generation of action potentials in pain sensitive nerve afferent fibers (nerve fibers which carry information towards the brain and spinal cord) of the trigeminal nerve.

Answer 1

Answer

Generally, the electrical impulses that travel along the axons can be projected in two ways—the afferent or efferent nerve fibers.

In the PNS, the afferent neurons somas are located in the ganglia, and their axons transmit the electrical impulses from ganglion to ganglion and eventually back to the spine.

Answer 2

In the PNS, afferent nerve fibers are referred to as sensory neurons, of which axons carry the sensory information from regions of the body to the spinal cord, whereas the efferent nerve fibers in the PNS are preganglionic and postganglionic motor neurons that carry the impulses of motor-movement signals
