What neurons are necessary for a spinal cord reflex arc?

Question

Quizplus · Accepted Answer

The sensory neurons detect a stimulus (such as a hot surface) and send the information to the spinal cord. The lower motor neurons, located in the spinal cord, respond by activating the appropriate muscles to withdraw from the stimulus (such as pulling your hand away from the hot surface). Therefore, sensory and lower motor neurons are necessary for a spinal cord reflex arc. Upper motor neurons and integrative neurons are not directly involved in the reflex arc.
