Answer;

-Sensory, motor, and interneurons

Explanation;

-Sensory neurons or afferent neurons carry signals from the outer parts of your body (periphery) into the central nervous system. They receive information from both external (through the senses) and internal (from muscles, organs and glands) environment.

-Interneurons are only located in CNS & connect between motor and sensory neurons. They exist only in the central nervous system (brain and spinal cord). They relay messages from sensory neurons to motor neurons and also bring message from various sources, organizing and integrating information.

-Motor neurons (efferent neurons) transmit neural messages from the brain to various areas of the body including muscles, internal organs and glands. They enable bodily movements, internal organs to be activated and glandular secretions to occur. They also Receive and act on messages received from interneurons.
