Carry messages to the brain & spinal cord from a receptor; afferent nerves

• A. Sensory nerves
• B. Efferent nerves
• C. Interneurons
• D. Motor nerves

Answer: (A)

Messages to the brain and spinal cord from a receptor are carried by sensory nerves, also called afferent nerves. These nerves detect signals such as touch, temperature, pain, and body position at receptors in the skin, muscles, and organs, and transmit that information toward the central nervous system. In contrast, efferent (motor) nerves send commands from the CNS to muscles or glands, and interneurons stay within the CNS to connect other neurons. So the described function matches sensory/afferent nerves best.
