Ask a question


Axon is one of the three large components of a neuron. It is a nerve fiber that transmits electrical impulses between neurons. The axon has several nerve endings in order to connect to several neurons simultaneously. Nerves are composed of axons. Myelin, which surrounds the axons in the central nervous system, serves to improve its performance. The axon is also in charge of transporting proteins between cells and synapses.
