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 incoming signals from other neurons. The cell body processes these signals. The axon is responsible for transmitting the electrical signal away from the cell body. Synaptic terminals are where the neuron communicates with the target cell.

Focus on the axon: The axon is a long, slender projection that conducts electrical impulses away from the neuron's cell body. This is the part of the neuron that transmits the electrical signal to the target cell.

Consider the role of the synapse: The synapse is the junction between the axon terminal of one neuron and the dendrite or cell body of another neuron or target cell. It is where the electrical signal is converted into a chemical signal to communicate with the target cell.

Conclude that the axon is the correct answer: Based on the functions of each part of the neuron, the axon is the component that transmits the electrical signal to the target cell, making it the correct answer to the question.
