WebAn axon typically develops side branches called axon collaterals, so that one neuron can send information to several others. These collaterals, like tree roots, split into smaller … WebMyelin is a lipid sheath that surrounds and protects axons to speed up the rate at which the electrical impulse travels along the axon. This lesson discusses the contents and function of myelin and the cells that myelinate axons in the central and peripheral nervous systems.
