Quizplus · Accepted Answer

Interneurons are responsible for processing sensory information and coordinating the appropriate motor response. In a reflex arc, sensory neurons receive the stimuli and send the signals to interneurons in the spinal cord or brain. Interneurons then transmit the signal to motor neurons, which then send the signal to the appropriate muscles to contract or relax. Therefore, the coordination between contraction of certain muscles and relaxation of others is mediated by interneurons.
