What structure carries impulses away from the cell body?

The structure that carries impulses away from the cell body is the axon. Axons are long, slender projections of a nerve cell that transmit electrical signals, known as action potentials, away from the soma (cell body) towards other neurons, muscles, or glands. The function of axons is crucial for the communication between different parts of the nervous system and the body.

While dendrites carry impulses toward the cell body, and the soma is the main body of the neuron that processes information, the axon is specifically designed to convey information away from the soma to ensure that signals can be sent efficiently over distances. The synapse, on the other hand, is the junction between two neurons through which impulses are transmitted, but it does not carry impulses itself. Thus, axons play an essential role in the overall functioning of the nervous system by facilitating the flow of information away from the neuron’s cell body.
