What is the function of an axon in a neuron?

• A. Receive impulses
• B. Transmit impulses away from the cell body
• C. Connect cells together
• D. Protect neurons

Answer: (B)

The function of an axon in a neuron is to transmit impulses away from the cell body. The axon serves as a long, slender projection that conducts electrical signals, known as action potentials, away from the neuron's cell body to other neurons, muscles, or glands. This is crucial for the functioning of the nervous system, as it allows for the rapid communication of information throughout the body.

Axons can vary in length and are often covered by a myelin sheath, which enhances the speed of impulse transmission. The process involves the depolarization and repolarization of the axonal membrane, leading to the propagation of the electrical signal. Understanding axonal function is essential because it highlights how neurons communicate and coordinate bodily functions and responses.
