High-resolution scanning electron microscopic study of cell organelles of the chick's vestibular ganglion.
The fine intracellular structures of the chick's vestibular ganglion were studied three-dimensionally using the scanning electron microscope (SEM) after freeze-fracturing with 50% dimethyl sulfoxide solution and placement in 0.1% osmium oxide solution. Three patterns of perikaryal myelination could be distinguished in the vestibular ganglion cells: heavily myelinated, lightly myelinated and unmyelinated. Intracellular organelles such as the Golgi apparatus, endoplasmic reticulum and mitochondria could be demonstrated clearly. The stereoscopic structures of the Schwann cells and nerve fibers were also clearly demonstrated.
