Webaxon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe. Most axons of vertebrates are enclosed in a myelin … WebNerve fibers are classified based on their thickness into small fibers and large fibers depending on how thick they are. Large fiber nerve cells have diameters more than about 5 micrometers, and small fibers are thinner. The large fibers are bigger because the axons are sheathed in fatty wrappings called “myelin”.
