Which neuron carries signals toward the central nervous system?

Explanation:
The main idea here is the direction of information flow in the nervous system. Signals toward the central nervous system come from sensory receptors and travel along afferent neurons. These sensory neurons bring input from the body or environment to the brain or spinal cord, such as touch, temperature, or pain. In contrast, efferent neurons carry commands from the CNS to muscles or glands to produce a response, and interneurons inside the CNS help process and relay that information. So the neuron that carries signals toward the central nervous system is the afferent neuron.
