The simplest form of nervous pathway which links receptors with effectors is known as the reflex arc. The reflex arc is responsible for reflex actions, which are automatic, involuntary responses to a particular stimulus. When a stimulus is detected by sensory receptors, the impulse travels along sensory nerves to the spinal cord, where it is processed by a small group of neurons called the reflex center. From there, the impulse travels along motor nerves to the effector muscles, which respond by contracting or relaxing. The reflex arc is a rapid and efficient way of responding to potentially harmful or dangerous stimuli without involving the conscious brain. Examples of reflex actions include pulling your hand away from a hot stove, blinking when an object comes close to your eye, or sneezing when dust irritates your nose.
