Scintigraphic Evaluation of Swallowing
Swallowing or deglutition is a process of propulsion of food from the oral cavity into the stomach. It is classified into oral, pharyngeal and esophageal stages according to the location of the bolus. The oral stage is subdivided into oral preparatory and oral propulsive stages which are under voluntary control, whereas the next two stages, the pharyngeal and esophageal stages, are involuntary, being under reflexive control.
