WebThe axon arises from the cell body at a small elevation called the axon hillock. The proximal part of the axon, adjacent to the axon hillock, is the initial segment. The cytoplasm of the axon (axoplasm) contains dense bundles of microtubules and neurofilaments (Figs. 2.1 and 2.5A, B). These function as structural elements, and the … WebThe nervous system is composed of two basic cell types: glial cells (also known as glia) and neurons.
