At the end of the lecture the student should be able to describe,definition of deglutition, infantile & mature swallowing.,anatomic consideration of pharynx & larynx.,three stages of deglutition.,swallowing movement. Learn about the voluntary, pharyngeal, & esophageal stages of swallowing. understand the physiology & nervous regulation of deglutition. Oral phase the process begins with contractions of the tongue and striated muscles of mastication. in the oral phase, a formed bolus is positioned in the middle of the tongue. the bolus is then pressed firmly against the tonsillar pillars, triggering the pharyngeal phase.

Four stages of mastication and deglutition • 1. oral prep: – food is placed in mouth – tongue responsible for manipulating • crush on hard palate • manipulates between teeth – mastication – mixed with saliva – buccinator contracts keeping food from entering buccal cavities. Lower esophageal sphincter (les) relaxation – the les relaxes to allow food into the stomach, then contracts to prevent acid reflux. peristalsis and swallowing control 1. swallowing (deglutition) control swallowing is divided into three phases, each with different control mechanisms: oral phase (voluntary controlled by the. Physiology of mastication and deglutition chapter 8. perry c. hanavan, au.d. mastication: processes involved in food preparation, including moving unchewed food onto the grinding surface of the teeth, chewing, it, and mixing it with saliva in preparation for swallowing. Deglutition involves the coordinated passage of food from the mouth to the stomach through three phases oral, pharyngeal, and esophageal. during the oral phase, tongue movements prepare and transfer food into a bolus.
