The correct simple spinal reflex arc is receptor, afferent neuron, integration center, efferent neuron, effector. This is the classic model for a simple reflex arc, where a stimulus is detected by a sensory receptor, which sends a message to the spinal cord is received by an afferent neuron. The afferent neuron then synapses with an interneuron in the integration center of the spinal cord, which in turn synapses with an efferent neuron. The efferent neuron carries the motor response signal to the effector, causing a muscle contraction or glandular secretion.
