One of the three basic parts of a neuron is the ________.
- A. axon
- B. myelin
- C. pons
- D. dura mater
Correct Answer: A
Rationale: A neuron consists of three basic parts: the cell body, dendrites, and axon. The axon is a long, slender projection that transmits nerve impulses away from the cell body to other neurons or target cells. Myelin is a protective sheath around some axons, the pons is a part of the brainstem, and the dura mater is a meningeal layer. Therefore, axon is the correct answer as it is one of the fundamental components of a neuron.
