Verified step by step guidance

Understand the structure of a neuron: Neurons are specialized cells that transmit information throughout the nervous system. They consist of several key parts: dendrites, a cell body (soma), an axon, and synaptic terminals.

Identify the function of each part: Dendrites receive signals from other neurons, the cell body processes these signals, and the axon transmits the signal away from the cell body to other neurons or muscles.

Focus on the axon: The axon is a long, slender projection of the neuron that conducts electrical impulses away from the neuron's cell body. This is the part responsible for sending signals to other neurons.

Consider the role of the synapse: The synapse is the junction between two neurons where the axon terminal of one neuron communicates with the dendrite or cell body of another neuron through neurotransmitters.

Conclude that the axon is the correct answer: Based on the functions of each part of the neuron, the axon is the portion that sends signals to other neurons, making it the correct answer to the problem.
