In the context of the organization of the nervous system, what is the primary function of an axon in a neuron?

• A. To transmit electrical impulses away from the cell body toward other neurons or muscles
• B. To store neurotransmitters for future use
• C. To provide metabolic support to the neuron
• D. To receive incoming signals from other neurons

Answer: (A)

Verified step by step guidance

1. Understand the basic structure of a neuron, which includes the cell body (soma), dendrites, and the axon.
2. Recall that dendrites primarily receive incoming signals from other neurons, acting like antennae.
3. Recognize that the axon is a long, slender projection that carries electrical impulses away from the cell body.
4. Know that these electrical impulses, called action potentials, travel along the axon to communicate with other neurons, muscles, or glands.
5. Conclude that the primary function of the axon is to transmit electrical impulses away from the cell body toward other neurons or muscles.
