Quizplus · Accepted Answer

The correct order for a typical reflex arc starts with the sensory receptor (3) detecting a stimulus. The sensory neuron (1) then carries the signal to the integrating center (4), usually the spinal cord or brain, where the information is processed. From there, the motor neuron (2) carries the signal to the effector (5), such as a muscle or gland, to produce a response.
