Download or read book The Esophagus written by Joel E. Richter and published by John Wiley & Sons. This book was released on 2021-07-13 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book Motor Function of the Pharynx, Esophagus, and Its Sphincters written by Ravinder Mittal and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Radiology of the Esophagus written by Marc S. Levine and published by . This book was released on 1989 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This definitive reference offers a comprehensive review of the radiology of esophageal disease. Details the use of double contrast techniques for recognizing subtle mucosal abnormalities and diagnosing early conditions--including the erosions of reflux esophagitis and the small lesions of early gastric cancer. Discusses the value of new cross-sectional imaging techniques such as CT and MRI for differential diagnosis and for staging malignant diseases.

Download or read book Horsemen of the Esophagus written by Jason Fagone and published by Crown. This book was released on 2006 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary Computer-Assisted Language Learning(CALL) is a comprehensive, one-volume work written by leading international figures in the field focusing on a wide range of theoretical and methodological issues. It explains key terms and concepts, synthesizes the research literature and explores the implications of new and emerging technologies. The book includes chapters on key aspects for CALL such as design, teacher education, evaluation, teaching online and testing, as well as new trends such as social media. The volume takes a broad look at CALL and explores how a variety of theoretical approaches have emerged as influences including socio-cultural theory, constructivism and new literacy studies. A glossary of terms to support those new to CALL as well as to allow those already engaged in the field to deepen their existing knowledge is also provided.Contemporary Computer-Assisted Language Learningis essential reading for postgraduate students of language teaching as well as researchers in related fields involved in the study of computer-assisted learning.

Download or read book Atlas of Esophagus and Stomach Pathology written by Scott R. Owens and published by Springer Science & Business Media. This book was released on 2013-09-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas of Esophagus and Stomach Pathology provides an image-based resource for those studying normal histology of the upper gastrointestinal tract, as well as the microscopic manifestations of developmental abnormalities, toxic insults, infectious diseases, inflammatory and autoimmune conditions, and neoplasia in the esophagus and stomach. Because modern gastrointestinal pathology practice centers on specimens obtained during endoscopic examination, the atlas focuses on biopsy pathology, providing “real-world” microscopic images and ancillary diagnostic studies for most commonly-encountered abnormalities and diseases affecting these two organs. The book is supplemented with endoscopic and special study images. Authored by nationally and internationally recognized pathologists, Atlas of Esophagus and Stomach Pathology is a valuable tool for both pathologists-in-training seeking to make “new acquaintances”, and practicing surgical pathologists in need of a quick visual reference in recalling “old friends” in the world of diagnostic gastrointestinal pathology.
