The correct answer is axon because it is the structure that directly carries nerve impulses away from the cell body of a neuron. The axon is crucial for sending signals to other neurons, muscles, or glands. In contrast, a synapse is the point of communication between neurons but does not conduct impulses itself. Dendrites receive incoming signals towards the cell body, and the myelin sheath is an insulating layer around the axon that facilitates faster signal transmission but does not play a role in transmitting impulses away from the cell body.

The axon is a long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body, making it essential for transmitting signals to other neurons or muscles.

A synapse is the junction between two neurons where communication occurs; however, it does not transmit impulses away from the cell body.

Dendrites are branches that extend from the neuron cell body and receive signals from other neurons, but they do not transmit impulses away.

The myelin sheath is a protective covering that surrounds the axon and helps speed up nerve impulse transmission, but it does not transmit impulses itself.
