Which part of the neuron transmits impulses away from the cell body?

The axon is the part of the neuron responsible for transmitting impulses away from the cell body. It serves as a long, slender projection that conducts electrical signals called action potentials to other neurons, muscles, or glands. The structure of the axon allows it to effectively transmit information over distances, making it crucial for communication within the nervous system.

Dendrites, on the other hand, are the branched projections of a neuron that receive signals from other neurons and convey this information toward the cell body. The synapse refers to the junction between two neurons where communication occurs, typically involving the release of neurotransmitters. The soma, or cell body, contains the nucleus and organelles of the neuron and integrates incoming signals but does not transmit impulses away from itself. Thus, the axon is specifically designed for transmitting impulses away from the cell body, which is why it is the correct answer.
