Which characteristic describes a cell body in a neuron?

• A. Contains sensory endings
• B. Found only in the central nervous system
• C. Conducts electrical impulses
• D. Releases neurotransmitters

Answer: (B)

The characteristic that best describes a cell body in a neuron is that it is found only in the central nervous system. The cell body, or soma, houses the nucleus and is crucial for the overall metabolic function of the neuron. It serves as the site where most of the neuron's cellular processes occur, including the synthesis of proteins and neurotransmitters essential for neural signaling. While cell bodies can also be found in the peripheral nervous system, their primary recognition as part of the central nervous system emphasizes their role in processing and integration of signals that occur in the brain and spinal cord. The other options refer to different parts or functions of neurons. For instance, sensory endings are associated with sensory neurons that convert external stimuli into electrical impulses, while the conduction of electrical impulses is primarily the function of the neuron's axon. Similarly, the release of neurotransmitters occurs at axon terminals, not specifically within the cell body itself. Therefore, the defining characteristic of the cell body being located in the central nervous system is a key organizational aspect of the neural structure.
