Yawning a unique involuntary respiratory movement that consists of a deep, lingering inhalation, during which the mouth, pharynx, and glottis open wide, followed by a rapid, energetic exhalation. An unconditioned reflex adaptive act, yawning is only found in mammals and is directed at improving the oxygen supply to organs when there is an accumulation of CO., in the blood. It occurs when there is fatigue, a prolonged stay in stuffy smoky premises, muscular inactivity, or drowsiness. It arises readily as an imitative act (infectiousness of yawning). Prolonged, painful, or spasmodic yawning may be a symptom of oxygen starvation of the brain (for example, during heavy blood loss) or other pathological conditions that require immediate medical attention. yawning
