The answer you are looking for is interneurons. They are found in the central nervous system (CNS) that is in the brain and spinal cord. Sensory neurons are your nerves that tell your brain what is going on within your body. They send impulses to your brain to let you know. As for motor neurons, they are located in your brain but they carry impulses to your muscles or glands. I hope I helped you!! Have a great day.
