Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The major role of the interneuron (association neuron) is to ____
A
carry information from the central nervous system to muscles and/or the viscera
B
form a lipid-protein (lipoprotein) cell membrane on the outside of axons
C
transmit nerve impulses from the skin and organs to the central nervous system
D
connect motor and sensory neurons in their pathways
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: -The primary function of interneurons is integration. They carry sensory information and regulate motor activity. More interneurons are activated when a response to stimuli is required to be complex. Interneurons are utilized in all higher functions, including learning, memory, cognition, and planning.

Detailed explanation-3: -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-4: -Answer and Explanation: Interneurons act as a middle man to connect the sensory and motor neurons in their pathways. They are responsible for transferring signals between sensory and motor neurons.
