Which conducts impulses from one part of the body to another?

• A. Afferent nervous system
• B. Neurons
• C. Efferent neurons
• D. Skeletal muscles

Answer: (B)

Neurons are specialized cells that transmit electrical impulses along their length, from one part of the body to another. They carry signals through dendrites, the cell body, and the axon to other neurons, muscles, or glands, enabling rapid communication throughout the nervous system. Skeletal muscles don’t conduct impulses themselves; they are the effectors that respond to neural signals by contracting. Afferent and efferent describe the direction of signaling (toward or away from the central nervous system), but the carriers of those impulses are the neurons. So the best answer is neurons.
