In stumptail monkeys from birth to adulthood, and in very young human infants, the epiglottis serves to guide the larynx upwardly behind the soft palate so it can lock into the nasopharynx and remain there during respiration. After early infancy in man the attainment of a larynx-nasopharynx connection is uniquely lost, causing the epiglottis to have no essential function.
从出生到成年的短尾猴以及非常年幼的人类婴儿,会厌起到引导喉部在软腭后方向上,从而使其能够锁定在鼻咽部并在呼吸时保持在那里的作用。在人类婴儿期之后,喉与鼻咽部的连接独特地消失,导致会厌没有基本功能。
