Axons are the primary transmission lines of the nervous system, and as bundles they form nerves. Some axons can extend up to one meter or more while others extend as little as one millimeter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across). The largest ma… WebThere is only one axon that projects from each cell body. It is usually elongated and because it carries impulses away from the cell body, it is called an efferent process. Axon An axon may have infrequent branches called axon collaterals. Axons and axon collaterals terminate in many short branches or telodendria. batik benang bintik
