During swallowing the nasopharynx is occluded by contraction of both tensor and levator palati. The larynx is elevated 2 to 3 cm by contraction of the infrahyoid muscles, stylopharyngeus and palatopharyngeus, coming to lie under the epiglottis. In addition, the aryepiglottic folds are approximated, causing total occlusion of the entrance to the larynx. This extremely effective protection of the larynx is capable of withstanding pharyngeal pressures as high as 80 kPa (800 cmH2O), which may be generated during swallowing.
吞咽时，腭帆张肌和腭帆提肌收缩，阻塞鼻咽部。舌骨下肌、茎突咽肌和腭咽肌收缩，使会厌下方的喉部抬高 2-3 厘米。此外，杓会厌襞对合，使喉部入口完全闭塞。这种极其有效的喉保护使其能够承受吞咽过程中产生的高达80 kPa (800 cmH2O)的咽部压力。

会厌下方？到会厌下方？
