Clusters of nerve cell bodies enclosed within a common connective tissue envelope in the spinal ganglia of the lizard and rat.

摘要: A careful search for groups of nerve cell bodies enclosed within a common connective envelope was made in the spinal ganglia lizard and rat using serial-section technique. Nerve sharing were found to be more (9.4%) than (5.6%). These arranged pairs, or, less frequently, three. At times, they appeared immediate contact, with no intervening satellite cells; at other, remained separated from one another by sheet. The clusters probably result arrest developmental processes ganglion. It is possible that, as arrangement here described, certain neurons electrically influence other sensory level
