Ganglionic
Definition:
(a.) Pertaining to, containing, or consisting of, ganglia or ganglion cells; as, a ganglionic artery; the ganglionic columns of the spinal cord.
Example Sentences:

(7) The death of retinal ganglion cells during development thus seems to serve 2 purposes: It provides for the quantitative matching of the ganglion cell population to the needs of its central projection fields, and, at the same time, it serves to selectively eliminate those cells whose axons project to inappropriate targets or to inappropriate regions within the correct target fields.
