Motor-neurons carry information in which direction?

Motor-neurons carry information in which direction?

• A. From the autonomic nervous system
• B. To the autonomic nervous system
• C. From the central nervous system
• D. To the central nervous system

Answer: (C)

Motor neurons are the efferent part of the nervous system, carrying commands from the brain and spinal cord to muscles and glands. Their cell bodies sit in the central nervous system, and their axons extend into the peripheral nervous system to reach their targets. Because the signal starts in the CNS and travels outward to effectors, the direction is from the central nervous system toward the body. The autonomic system is simply one set of targets for these motor commands, but the overall flow of motor information remains away from the CNS, not toward it.
