It is composedfrom within out of (1) an axis cylinder, (2) a myelin sheath, and(3) a neurilemma. (1) The axis cylinder is the essential part ofthe nerve. It is the prolongation of the neuraxon of a nerve celland consists of protoplasm. It is itself made up of fine fibrillae(primitive fibrillae) which run longitudinally. By means of re-agents, a transverse striation can be seen also. (2) The myelinsheath, medul
