Download and read online ebook Motor Function of the Pharynx, Esophagus, and Its Sphincters write by Ravinder Mittal. This book was released on 2011. Motor Function of the Pharynx, Esophagus, and Its Sphincters available in PDF, EPUB and Kindle. Deglutition or a swallow begins as a voluntary act in the oral cavity but proceeds autonomously in the pharynx and esophagus. Bilateral sequenced activation and inhibition of more than 25 pairs of muscles of mouth, pharynx, larynx, and esophagus is required during a swallow. A single swallow elicits peristalsis in the pharynx and esophagus along with relaxation of upper and lower esophageal sphincters. Multiple swallows, at closely spaced time intervals, demonstrate deglutitive inhibition; sphincters remain relaxed during the entire period, but only the last swallow elicits peristalsis. Laryngeal inlet closure or airway protection is very important during swallow. Upper part of the esophagus that includes upper esophageal sphincter is composed of skeletal muscles, middle esophagus is composed of a mixture of skeletal and smooth muscles, and lower esophagus, including lower esophageal sphincter, is composed of smooth muscles. Peristalsis progresses in seamless fashion, despite separate control mechanism, from the skeletal to smooth muscle esophagus. The esophagus's circular and longitudinal muscle layers contract synchronously during peristalsis. Sphincters maintain continuous tone; neuromuscular mechanisms for tonic closure in the upper and lower esophageal sphincters are different. Lower esophageal sphincter transient relaxation, belching mechanism, regurgitation, vomiting, and reflux are mediated via the brain stem.

This book was released on 2021-07-13. The Esophagus available in PDF, EPUB and Kindle. THE ESOPHAGUS The Esophagus investigates the anatomy, physiology, and pathology of the esophagus. This sixth edition, revised and updated throughout, also explores the diagnosis and treatment of various esophageal conditions. It includes treatment guidelines approved by the two largest gastroenterology societies, the ACG and AGA, as befits a work co-edited by two former presidents of those organizations. Advancements in diagnostics are presented, as are developments in the surgical and drug therapies. Presented in full colour, and boasting an unrivalled team of editors and contributing authors, The Esophagus Sixth Edition will find a home wherever the anatomy, physiology, and pathology of the esophagus are studied and taught. This book is accompanied by a website containing all the figures from the book in PowerPoint format. www.wiley.com/go/richter/esophagus6e Praise for the Fifth Edition: “There is absolutely no doubt that this edition of the textbook will maintain its status as the go-to reference for esophageal conditions, and will remain a highly utilized and clinically useful resource for novice and experienced physicians and surgeons alike.” (Gastroenterology, 1 July 2013)

Download and read online ebook Principles of Deglutition write by Reza Shaker. This book was released on 2012-09-20. Principles of Deglutition available in PDF, EPUB and Kindle. Principles of Deglutition is the first in class comprehensive multidisciplinary textbook to encompass the entire field of normal and disordered deglutition. It is designed as the definitive text for all those who desire to further their knowledge of the dynamic and expanding field of deglutology. The text is created to serve as a treasured reference for clinicians, educators and trainees from such diverse backgrounds as gastroenterology, speech language pathology, otolaryngology, rehabilitation medicine, radiology and others. Principles of Deglutition brings together the state-of-knowledge from 12 disciplines involved in dysphagia through contributions of over one hundred thought leaders and master clinicians for the benefit of patients and providers alike. It concisely organizes the wealth of knowledge that exists in each of the contributing disciplines into one comprehensive information platform. Principles of Deglutition provides a one-stop destination for members of all specialties to obtain state-of-the-art and critically reviewed information regarding deglutition physiology, pathophysiology, diagnosis and management. It delivers a comprehensive and in depth review of deglutition related cerebral cortical, brainstem, peripheral nerves, and neuromuscular mechanisms, advanced diagnostic modalities and standard of care and cutting edge medical, rehabilitative and surgical treatments. It is an essential reference for all deglutologists.
