Abstract
Deglutition, the act of swallowing, is a complex process that involves coordinated movements within the oral cavity, pharynx, larynx, and esophagus. A normal swallow prepares and transfers food and liquids from the mouth to the stomach with the coordination of more than 30 muscles (Shaw and Martino, Otolaryngol Clin North Am 46:937–56, 2013). There are four distinct phases of swallowing: oral preparatory, oral transport, pharyngeal, and esophageal. These swallowing phases are coordinated by six cranial nerves and three peripheral nerves. Understanding the normal anatomy and physiology of swallowing is pertinent to successfully diagnosing and treating swallowing dysfunctions. The anatomy and embryology of the swallowing process are reviewed.
