Specimens were examined by light and electron microscopy, and a good correlation was found between the data obtained by the two techniques … WebEarly in development, axons are narrow processes that contain relatively few neurofilaments. Those axons that become myelinated accumulate more neurofilaments, which drives the expansion of their caliber. After an axon has grown and connected with its target cell, the diameter of the axon may increase as much as fivefold.
