Transverse section through myelinated fibers within a nerve fascicle (Triple stain). This is a higher power view of the preceding section. Blue endoneurium surrounds myelin sheaths. Myelin neurokeratin appears as well defined red circles. Axons (asterisks) within myelin rings generally are not distinct with this stain. Lemmocyte cytoplasm or nuclei are occasionally visible (e.g., below the lower, right asterisk).
