Quizplus · Accepted Answer

The correct sequence in a reflex arc is as follows: The receptor detects a stimulus and sends a signal to the sensory nerve. The sensory nerve carries the signal to the interneuron in the spinal cord. The interneuron processes the information and sends a signal through the motor nerve. The motor nerve carries the signal to the effector, which carries out the response. Therefore, the correct sequence is receptor, sensory nerve, interneuron, motor nerve, effector, which is only represented in option C.
