Sensory neurons carry informations

• 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: (D)

Sensory neurons carry information toward the central nervous system. These afferent neurons pick up signals from receptors in the skin, organs, and sense organs and send them to the brain and spinal cord for processing. That direction—input from the body toward the CNS—lets the brain interpret what’s happening and initiate appropriate responses. In contrast, motor (efferent) neurons carry instructions from the CNS to muscles and glands. Some sensory input does come from autonomic receptors, and some signals travel within autonomic pathways, but the defining role of sensory neurons is to bring information to the CNS, which is why that statement is the best fit.
