Anatomy And Physiology Of Swallowing

Food passage from the oral cavity to stomach and airway protection. The four stage model for drinking and swallowing liquid and the process model for eating and swallowing solid food.

Muscles Of Chewing And Swallowing Physiology

The normal swallow in humans was originally described with a three stage sequential model.

Anatomy and physiology of swallowing. Eating and swallowing are complex behaviors involving volitional and reflexive activities of more than 30 nerves and muscles. 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. 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.

Food processing and bolus formation occurs in the oral cavity proper that is the space between the upper and lower dental arches. 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. Anatomy of the oral cavity.

They have two crucial biologic features. Two paradigmatic models are commonly used to describe the physiology of normal eating and swallowing. 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.

Deglutition process of swallowing oropharyngeal dysphagia oral pharyngeal espohageal anatomy esopharyngeal dysphagia. The course is designed to give clinicians the confidence to discuss normal anatomy and physiology of all phases of adult swallowing with patients caregivers and medical professionals and to use their knowledge to accurately assess swallow function. Anatomy and physiology of feeding and swallowing.
