Swallowing Diagram For Patient Education Normal swallowing requires a coordinated effort of over thirty muscles, the central nervous system, and five cranial nerves. other key anatomical structures involved in this process are the nose, nasal cavity, oral cavity, and pharynx. this article explores the relevant anatomy and physiology of normal swallowing. You can therefore manipulate, subconsciously, the soft palate—for instance, to yawn, swallow, or sing (see figure 23.3.1). figure 23.3.1 – mouth: the mouth includes the lips, tongue, palate, gums, and teeth. a fleshy bead of tissue called the uvula drops down from the center of the posterior edge of the soft palate.
The Mouth Pharynx And Esophagus Anatomy And Physiology Ii The process of swallowing, also known as deglutition, involves the movement of substances from the mouth (oral cavity) to the stomach via the pharynx and esophagus. swallowing is an essential and complex behavior learned very early in development. this pathway shares anatomy with the airway; thus, in addition to directing food into the digestive tract, the swallowing mechanism serves as a. Deglutition or swallowing is an innate function. swallowing sounds like a simple physiological human function, but it is a complex, multifaceted process involving a variety of muscles and nerves. it is the starting point for the peristaltic transport of food to the stomach. deglutition in humans can be of three distinct phases: oral phase, pharyngeal phase, and esophageal phase, of which the. Stages of swallowing. the process of swallowing is an essential part of the digestive process. food is first ingested into the mouth and then broken down in the mouth by chewing, or mastication, tongue movements, saliva, and teeth grinding until it becomes a bolus, a soft mass. the food bolus is soft enough that it can easily be swallowed and. Eating and swallowing are compex behaviors including both volitional and reflexive activities involving more than 30 nerves and muscles. 1. the anatomy of the oral cavity, pharynx, larynx and innervations of the muscles are shown in figure 1 and table 1. the tongue has both oral and pharyngeal surfaces. the oral cavity is separated from the.

Oropharynx, in the middle of your throat. it contains your tonsils at the base of your tongue and connects to your oral cavity. air, food and fluid all pass through your oropharynx. hypopharynx, at the bottom of your pharynx. it regulates how food moves to your esophagus and on to your digestive system, and how air moves to your lungs. The pharynx assists in the shared functions of respiration and swallowing (deglutition); coordination between these functions is of great importance. this article reviews the phases of the normal swallow and describes relevant applied anatomy and physiology to assist in the understanding of what is a complex and multifactorial process.
