SEARCH. A receptor, a sensory neuron, a motor neuron, The motor neuronâs innervation of the peripheral nervous system, and at least one association neuron from the central nervous system are the ingredients to a conduction passageway of the reflex arc.he reflex arc is made up of five basic elements. These include the receptor, the sensory neuron, center, the motor neuron, and the effector.
