$A$ functional unit consisting of a receptor neural pathway and an effector neuron

(A) reflex arc is the neural pathway that mediates a reflex action.It consists of a receptor,a sensory (afferent) neuron,an integration center (usually in the spinal cord),a motor (efferent) neuron,and an effector organ (muscle or gland).Therefore,it is a functional unit consisting of a receptor neural pathway and an effector neuron.
