They are grayish and faintly striated, and consistof axis cylinders, with a thin, homogeneous, nucleated sheath lyingdirectly upon them. This sheath, however, cannot often be demon-strated (Schaefer). Naked axis cylinders are found in the peripheral terminationsof nerves as well as in the brain and cord.
