Nerve impulses are carried to another part of the body by a neuron's (nerve cell):
- A. dendrites
- B. axon
- C. neuron cell body
- D. synapse
Correct Answer: B
Rationale: The axon is the part of a neuron responsible for carrying nerve impulses away from the cell body to other neurons, muscles, or glands. It is a long, slender projection that conducts electrical signals, known as action potentials, to the axon terminals. At the terminals, the signal triggers the release of neurotransmitters into the synapse, facilitating communication with the next neuron or target cell. The axon is essential for transmitting information across the nervous system.
