                                In biology, a reflex arc is an automatic response to a stimulus, and it is made possible by a specific pathway of nerve cells. However, the roles of these cells are often confused, particularly the core question: is an afferent neuron an effector? The straightforward answer is no, and understanding why reveals the fundamental architecture of the human nervous system.
