Note: An ordinary nerve is made up of several bundles of nerve fibers, each bundle inclosed in a special sheath (the perineurium) and all bound together in a connective tissue sheath and framework (the epineurium) containing blood vessels and lymphatics.

A ganglion cell is a cell found in a ganglion. The term is also sometimes used to refer specifically to:
- a retinal ganglion cell (RGC) found in the ganglion cell layer of the retina;
- cells that reside in the adrenal medulla, where they are involved in the sympathetic nervous system's release of epinephrine and norepinephrine into the blood stream; and
- cells of the sympathetic ganglia, parasympathetic ganglia, and spiral ganglia.
- cells of the parasympathetic ganglia
- cells of the spiral ganglia

He is also a chemist of considerable eminence, and I suppose in the subtle and complex jungle of riddles that centres about the ganglion cell and the axis fibre there are little cleared places of his making, little glades of illumination, that, until he sees fit to publish his results, are still inaccessible to every other living man.
