Click here for larger view.

High magnification view of a small portion of one nerve fascicle cut in cross section. The axon (Ax) is pale and central within each myelinated nerve, and is surrounded by concentric wrappings of the neurolemmal cell plasma membrane - myelin (My). The junction between two adjoining neurolemmal cells presents a slight gap - Node of Ranvier (NR). Also seen here are the oval nuclei of the neurolemmal cells (NCN).
