Longitudinal sections of nerves.
In the upper figure: two nerve fascicles separated by a layer of connective tissue.
Nerve (longitudinal section). Staining: HE. Small magnification.
In the lower figure, at a higher magnification, notice inside the fibers a large amount of clear spaces that contained myelin that was dissolved during the tissue preparation.
Segments of axonscan be seen as thin darker stained stretches of stripes inside the fibers, some of them pointed by lines.
Longitudinal nerve sections can be confused with smooth muscle tissue or dense regular connective tissue. Review these tissues and compare them with nerves.
Nerve (longitudinal section). Staining: HE. Medium magnification.
