What is the job of an interneuron?
A
receiving messages from the environment
B
carrying information from the brain and spinal cord to muscles
C
passing messages between sensory and motor neurons
D
None of the above
Explanation: 

Detailed explanation-1: -Interneurons acts as a “middle-man” between afferent, or sensory, neurons, which receive signals from the peripheral nervous system, and efferent, or motor, neurons, which transmit signals from the brain. It also connects to other interneurons, allowing them to communicate with one another.

Detailed explanation-2: -Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system. Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body. Interneurons connect various neurons within the brain and spinal cord.

Detailed explanation-3: -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. They are multipolar, just like motor neurons.

Detailed explanation-4: -Sensory cells carry afferent impulses to a central interneuron, which makes contact with a motor neuron. The motor neuron carries efferent impulses to the effector, which produces the response.

Detailed explanation-5: -Interneurons: send information between sensory neurons and motor neurons. Most interneurons are located in the central nervous system.
