Which component transmits impulses away from the cell body?

Explanation:
The part that transmits impulses away from the cell body is the axon. The axon carries the electrical signal, called an action potential, from the soma (cell body) toward axon terminals to communicate with other neurons or muscles. Dendrites, by contrast, receive signals from other cells. The myelin sheath wraps around the axon to speed up signal transmission, helping the impulse jump between gaps called nodes of Ranvier, but it does not itself carry the signal away. A neuron is the whole nerve cell that includes dendrites, a cell body, and an axon.
