5. The effector, muscle fibers or glands, responds to the efferent impulses by contracting or secreting a product, respectively. Figure 1. Simple reflex arc. Components of all human reflex arcs: receptor, sensory neuron, integration center (one or more synapses in CNS), motor neuron, and effector.owever, most reflexes are more complex and polysynaptic, involving the participation of one or more association neurons in the reflex arc pathway. A three-neuron reflex arc (flexor reflex) is diagrammed in Figure 2b.
