The Esophagus and Pharynx in Action: A Study of Structure in Relation to Function

Abstract

According to the author, the primary purpose of the research described in this handsomely illustrated monograph was to throw light on the closing mechanism at the cardia. After the constrictor cardiae had been found in contraction in specimens that had remained in the state of regurgitation, Lerche's study was extended to an investigation of the relation of structure to function in the stretch of alimentary canal from cardia to pharynx during acts of regurgitation and deglutition. The various theories dealing with the closing mechanism at the cardia still suggest that a variety of problems pertaining to anatomy and physiology remain unsettled. Although it has limited appeal, this monograph should interest anatomists, pathologists and surgeons who are concerned with the relation of structure to normal and disturbed function of the esophagus and pharynx and with the action of the upper esophagus and pharynx.
