| Description: Illustration of the anatomy of a normal subject (A) and a patient with sleep apnea (B). The upper airway is smaller and the soft palate is longer in the patient with sleep apnea, clearly blocking the airway. The amount of subcutaneous fat (shown in yellow at the back of the neck and under the chin) is greater in the apneic patient than in the normal subject. In a diagram of a non-obstructed airway, the airways from the nose to the throat are completely clear. In the diagram of a patient with sleep apnea, the following parts of the anatomy sit farther back and block the airway. tongue, epiglottis, subcutaneous fat under the chin, hard palate, and soft palate.
