Detailed explanation-1: -Interneurons . As the name suggests, interneurons are the ones in between-they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity.

Detailed explanation-2: -A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain.

Detailed explanation-3: -A neuron that transmits the impulse from the sensory neuron to a motor neuron is a relay neuron. Relay neuron allows sensory and motor neurons to communicate with each other.

Detailed explanation-4: -The PNS is made up of two divisions: the somatic nervous system and the autonomic nervous system. The somatic system contains sensory and motor neurons. It sends and receives sensory information and motor signals.

Detailed explanation-5: -Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS. They usually have long dendrites and relatively short axons. Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands.
