Final answer:
Interneurons are found throughout the nervous system and act as connectors between sensory and motor neurons. They can be located in both the CNS and the PNS.
Step-by-step explanation:
Interneurons are found throughout the nervous system, not just in the brain or spinal cord. These neurons act as connectors between sensory and motor neurons, transmitting nerve impulses back and forth.
They can be located in both the central nervous system (CNS) and the peripheral nervous system (PNS).
