Answer:
All of these are part of the central nervous system
Step-by-step explanation:
All three types of neurons—relay, motor, and sensory—are part of the central nervous system. Relay neurons carry signals from one part of the nervous system to another, motor neurons carry signals from the brain to the muscles, and sensory neurons carry signals from the senses to the brain. Together, these neurons form a complex network that allows the body to communicate with itself and the environment.
