Pathological condition of the nervous system that ascends from the lower part of the body to the upper.  

Direct infection of peripheral nerves by the human immunodeficiency virus (HIV) resulting in sensory and motor changes due to destruction of axons or their myelin covering. Acute or chronic inflammatory myelin damage may be the first sign of peripheral nerve involvement. Patients display gradual or abrupt onset of motor weakness and diminished or absent reflexes.…

A neuron that mediates impulses between a sensory and a motor neuron.  

Neuroma found in the mucosa and submucosa of the appendix.  

Neuroma composed principally of unmyelinated nerve fibers.  

Neuroma occurring on the nerves of a stump after amputation. A small, sensitive, and painful growth that can occur at the severed end of a nerve after a limb has been amputated. A neuroma that develops in the remnant of an amputated limb. This creates a sore, sensitive spot, potentially complicating the use of a…

Inflammation of the inner portion of a nerve. A type of neuritis that impacts the central axis of a nerve.  

Neuritis moving upward along a nerve trunk away from the periphery. Neuritis that originates at the body’s periphery and progresses along the nerve toward the brain or spinal cord.  

A nerve fiber that releases norepinephrine at its synapse when an impulse is transmitted. Most postganglionic fibers of the sympathetic division are adrenergic.  

A nerve (usually an autonomic sympathetic nerve) conducting impulses that bring about constriction of a blood vessel.
