The pharyngeal phase of deglutition is the most rapid, being usually of less than a second's duration, and for this reason has been difficult to analyze fully. The forces involved in the propu...

Brain stem control of swallowing: neuronal network and cellular mechanisms.

Swallowing movements are produced by a central pattern generator located in the medulla oblongata. It has been established on the basis of microelectrode recordings that the swallowing network includes two main groups of neurons. One group is located within the dorsal medulla and contains the generator neurons involved in triggering, shaping, and timing the sequential or rhythmic swallowing pat...

Mechanisms of airway protection during retching, vomiting, and swallowing.

We investigated the mechanisms of airway protection and bolus transport during retching and vomiting by recording responses of the pharyngeal, laryngeal, and hyoid muscles and comparing them with responses during swallowing and responses of the gastrointestinal tract. Five dogs were chronically instrumented with electrodes on the striated muscles and strain gauges on smooth muscles. Retching an...
