Step 1: Understand the structure of a neuron. A neuron is composed of several key parts: dendrites, cell body (soma), axon, and axon terminals. Each part has a specific function in transmitting nerve signals.
Step 2: Identify the function of the axon. The axon is a long, slender projection of the neuron that conducts electrical impulses away from the cell body toward other neurons, muscles, or glands.
Step 3: Compare the axon to other parts of the neuron. Dendrites receive signals from other neurons, the cell body processes these signals, and the axon terminals transmit the signals to the next neuron or target tissue.
Step 4: Examine the diagram provided in the problem. Locate the labeled part that matches the description of the axon—a long, thin structure extending from the cell body.
Step 5: Match the labeled part in the diagram to the correct answer choice. Based on the description and function of the axon, the correct answer is C. Axon.
