Anatomy Of Swallowing

The teeth are used to grind and chop up food into tiny pieces while the glands in the mouth moisten the food with saliva. If the uvula fails to completely cover the nasopharynx while swallowing.

Swallowing refers to the entire act of deglutition from placement of food in the mouth through the oral and pharyngeal stages of the swallow until the material enters the esophagus through the cricopharyngeal juncture.

Anatomy of swallowing. Swallowing sometimes called deglutition in scientific contexts is the process in the human or animal body that allows for a substance to pass from the mouth to the pharynx and into the esophagus while shutting the epiglottis. Anatomy physiology of swallowing the act of swallowing degluttition is an intricate action involving the integration of a complex series of sensory and motor responses. Food processing and bolus formation occurs in the oral cavity proper that is the space between the upper and lower dental arches.

Part of the mechanism is under active control while the rest is under autonomic control. The oral phase of swallowing occurs in the oral region that consists of the lips cheeks teeth gums oral cavity hard and soft palate and the palatine tonsils. Some of the common problems affecting this part of the throat anatomy are.

The structures involved with the process of swallowing include the tongue teeth epiglottis and esophagus. Swallowing is an important part of eating and drinking. This is a condition in which the uvula does not close.

The tongue has both oral and pharyngeal surfaces. Swallowing is divided into three stages. Pharyngeal phase involuntary movement of the bolus from the oropharynx into the esophagus.

Vpi or the velopharyngeal insufficiency. The anatomy of the oral cavity pharynx larynx and innervations of the muscles are shown in figure 1 and table 1. In the first stage of swallowing the tongue pushes the food into the throat.

Anatomy of the oral cavity. Deglutition process of swallowing oropharyngeal dysphagia oral pharyngeal espohageal anatomy esopharyngeal dysphagia. The act of swallowing must occur in a sequential and coordinated fashion in order to propel the food bolus into the esophagus and stomach without penetration into the larynx voice box and airway lungs.

Eating and swallowing are compex behaviors including both volitional and reflexive activities involving more than 30 nerves and muscles. Swallowing is the mechanism by which food is transported from the mouth to the stomach. This article shall consider the process of swallowing and some clinical conditions that may result from the process going wrong.

Oral phase voluntary movement of the bolus from the oral cavity into the oropharynx. This movement is controlled by the nervous system and involves both voluntary and involuntary muscle contractions. Swallowing is the process by which food moves from the mouth to the stomach.

Esophageal phase involuntary movement of the bolus through the. Infection caused due to bacteria and viruses.
