Observations on the ultrastructure of the axon hillock and initial axon segments of vestibular ganglion cells in the cat.
The axon hillock and initial axon segments of the vestibular ganglion cells in the cat were studied electron microscopically. The results revealed that the two cell processes are not completely comparable from morphological point of view. One of them is larger, with a more straight course, the axoplasm of the initia segment contains mainly longitudinally arranged neurotubules. The second cell process appears smaller in size, the initial segment have a curved course.
