NERVOUS SYSTEM

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. 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: -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: -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-4: -Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons. Often, they form complex circuits that help you to react to external stimuli.

Detailed explanation-5: -Sensory cells carry input from the receptor (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.
