  1. knee-jerk reflex

    The knee-jerk reflex is a type of automatic response, known technically as a monosynaptic reflex, that occurs when the tendon just below the kneecap is struck. This causes the quadriceps muscle to stretch, which in turn stimulates nerve impulses that lead to contraction of the muscle, causing the leg to kick forward. It is commonly tested by doctors with a small rubber hammer during physical examinations to assess the condition of the nervous system and motor function.
