空气和食物的通道在咽部交叉。在呼吸时，空气可以通过鼻子或嘴巴流动，但总是通过咽。在吞咽过程中，咽从气道变为食物通道。咽部吞咽时，通过腭咽和喉部闭合使咽与鼻腔和下气道分离。在咀嚼过程中，食物丸在吞咽开始前在咽中积累。口腔、咽部和喉部的结构在呼吸、说话、咀嚼和吞咽中起着多种作用。因此，呼吸、咀嚼和吞咽之间进食的精细时间协调对于提供适当的食物营养和防止肺部误吸至关重要。本文将回顾咀嚼和吞咽过程中口腔、咽和喉结构运动的时空协调性，以及呼吸、咀嚼和吞咽之间的时间协调性。
The pathways for air and food cross in the pharynx. In breathing, air may flow through either the nose or the mouth, it always flows through the pharynx. During swallowing, the pharynx changes from an airway to a food channel. The pharynx is isolated from the nasal cavity and lower airway by velopharyngeal and laryngeal closure during the pharyngeal swallow. During mastication, the food bolus accumulates in the pharynx prior to swallow initiation. The structures in the oral cavity, pharynx and larynx serve multiple functions in breathing, speaking, mastication and swallowing. Thus, the fine temporal coordination of feeding among breathing, mastication and swallowing is essential to provide proper food nutrition and to prevent pulmonary aspiration. This review paper will review the temporo-spatial coordination of the movements of oral, pharyngeal, and laryngeal structures during mastication and swallowing, and temporal coordination between breathing, mastication, and swallowing.
