Download or read book Enteric Glia written by Brian D. Gulbransen and published by Biota Publishing. This book was released on 2014-07-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enteric nervous system (ENS) is a complex neural network embedded in the gut wall that orchestrates the reflex behaviors of the intestine. The ENS is often referred to as the “little brain” in the gut because the ENS is more similar in size, complexity and autonomy to the central nervous system (CNS) than other components of the autonomic nervous system. Like the brain, the ENS is composed of neurons that are surrounded by glial cells. Enteric glia are a unique type of peripheral glia that are similar to astrocytes of the CNS. Yet enteric glial cells also differ from astrocytes in many important ways. The roles of enteric glial cell populations in the gut are beginning to come to light and recent evidence implicates enteric glia in almost every aspect of gastrointestinal physiology and pathophysiology. However, elucidating the exact mechanisms by which enteric glia influence gastrointestinal physiology and identifying how those roles are altered during gastrointestinal pathophysiology remain areas of intense research. The purpose of this e-book is to provide an introduction to enteric glial cells and to act as a resource for ongoing studies on this fascinating population of glia. Table of Contents: Introduction / A Historical Perspective on Enteric Glia / Enteric Glia: The Astroglia of the Gut / Molecular Composition of Enteric Glia / Development of Enteric Glia / Functional Roles of Enteric Glia / Enteric Glia and Disease Processes in the Gut / Concluding Remarks / References / Author Biography

Download or read book Glia in Health and Disease written by Tania Spohr and published by BoD – Books on Demand. This book was released on 2020-05-20 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book will highlight the role played by glial cells in the central and peripheral nervous systems in both healthy and unhealthy individuals. Among all processes involved, we will discuss the importance of the enteric nervous system in the control of gut homeostasis, in the interaction with the immune system, and its participation in pathological conditions such as metabolic syndrome. We will also look at the relevance of astrocytes during synaptic transmission and the regulation of plasticity by releasing gliotransmitters. Ultimately, we will highlight the influence of astrocytes during the development of a number of neurodegenerative diseases, such as multiple sclerosis and Alzheimer’s disease, focusing on how the serum levels of the astrocytic protein S100B can be used as a biomarker for clinical decisions.

Download or read book Transcriptional Control of Neural Crest Development written by Brian Nelms and published by Biota Publishing. This book was released on 2010-02-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neural crest is a remarkable embryonic population of cells found only in vertebrates and has the potential to give rise to many different cell types contributing throughout the body. These derivatives range from the mesenchymal bone and cartilage comprising the facial skeleton, to neuronal derivatives of the peripheral sensory and autonomic nervous systems, to melanocytes throughout the body, and to smooth muscle of the great arteries of the heart. For these cells to correctly progress from an unspecifi ed, nonmigratory population to a wide array of dynamic, differentiated cell types—some of which retain stem cell characteristics presumably to replenish these derivatives—requires a complex network of molecular switches to control the gene programs giving these cells their defi ning structural, enzymatic, migratory, and signaling capacities. This review will bring together current knowledge of neural crest-specifi c transcription factors governing these progressions throughout the course of development. A more thorough understanding of the mechanisms of transcriptional control in differentiation will aid in strategies designed to push undifferentiated cells toward a particular lineage, and unraveling these processes will help toward reprogramming cells from a differentiated to a more naive state.

Download or read book Functional Dyspepsia written by Kazunari Tominaga and published by Springer. This book was released on 2018-08-20 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research and outcomes presented in this book gather evidence concerning both the pathogenesis and treatment of functional dyspepsia. It provides the latest information on this common non-organic disease, indicating its characteristic pathogenesis based on the brain-gut interaction and micro-environment and evidence gleaned from clinical treatment. Since the pathogenesis is associated with psychology, neurology, endocrinology and bacteriology in addition to gastroenterological physiology, it is often intractable and finding a suitable treatment rationale is challenging. Furthermore, the pathogenesis varies around the world and the efficacy of treatment using standard drugs varies among different populations worldwide; accordingly, this book highlights evidence gained in clinical trials in Japan. Functional Dyspepsia is a milestone produced by respected experts. Addressing unique topics and new findings of treatment including challenging and/or future rationales, it offers an invaluable resource for general clinicians, gastroenterologists, and basic researchers alike.

Download or read book Neural Control of Gastrointestinal Function written by David Grundy and published by Morgan & Claypool Publishers. This book was released on 2011-12 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gastrointestinal tract is a long, muscular tube responsible for the digestion of food, assimilation of nutrients and elimination of waste. This is achieved by secretion of digestive enzymes and absorption from the intestinal lumen, with different regions playing specific roles in the processing of specific nutrients. These regions come into play sequentially as ingested material is moved along the length of the GI tract by contractions of the muscle layers. In some regions like the oesophagus transit it rapid and measured in seconds while in others like the colon transit is measured in hours and even days, commensurate with the relative slow fermentation that takes place in the large bowel. An hierarchy of controls, neural and endocrine, serve to regulate the various cellular targets that exist in the gut wall. These include muscle cells for contraction and epithelial cells for secretion and absorption. However, there are complex interactions between these digestive mechanisms and other mechanisms that regulate blood flow, immune function, endocrine secretion and food intake. These ensure a fine balance between the ostensibly conflicting tasks of digestion and absorption and protection from potentially harmful ingested materials. They match assimilation of nutrients with hunger and satiety and they ensure that regions of the GI tract that are meters apart work together in a coordinated fashion to match these diverse functions to the digestive needs of the individual. This ebook will provide an overview of the neural mechanisms that control gastrointestinal function.

Download or read book Developmental Biology of Gastrointestinal Hormones written by M. Wabitsch and published by Karger Medical and Scientific Publishers. This book was released on 2017-08-16 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gut not only represents the largest endocrine organ of the human body but is also profoundly involved in the control of metabolism through peptide hormones. Therefore, gastrointestinal hormones are acting via autocrine, paracrine, and classical endocrine pathways and regulate e.g. digestion, hunger, and satiety. Furthermore, they are important regulators of body weight, growth, and glucose metabolism, as well as of mood and behavior. Physicians and scientists in the field of pediatric endocrinology and diabetes, as well as in pediatric gastroenterology, require an extensive understanding of the origin of enteroendocrine cells, factors controlling their differentiation, hormone gene expression, secretion, function and, finally, the complex interaction with other organs, especially the central nervous system. In order to meet these needs, experts in the field have written up-to-date, comprehensive, and illustrated reviews presenting the current knowledge in the field of gastrointestinal endocrinology with a pediatric view. Those reviews comprise this latest volume of Endocrine Development.

Download or read book The Neural Crest written by Nicole Le Douarin and published by Cambridge University Press. This book was released on 1999-11-28 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.

Book excerpt: “Persuasive, impassioned. . . hopeful news [for those] suffering from functional bowel disease.” — New York Times Book Review Dr. Michael Gershon’s groundbreaking book fills the gap between what you need to know—and what your doctor has time to tell you. Dr. Michael Gershon has devoted his career to understanding the human bowel (the stomach, esophagus, small intestine, and colon). His thirty years of research have led to an extraordinary rediscovery: nerve cells in the gut that act as a brain. This "second brain" can control our gut all by itself. Our two brains—the one in our head and the one in our bowel—must cooperate. If they do not, then there is chaos in the gut and misery in the head—everything from "butterflies" to cramps, from diarrhea to constipation. Dr. Gershon's work has led to radical new understandings about a wide range of gastrointestinal problems including gastroenteritis, nervous stomach, and irritable bowel syndrome. The Second Brain represents a quantum leap in medical knowledge and is already benefiting patients whose symptoms were previously dismissed as neurotic or "it's all in your head."

Download or read book Neuroglia Function and Pathology written by Alexei Verkhratsky and published by Elsevier. This book was released on 2023-05-12 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diverse specialised neuroglial cells guarantee the development, preservation, and health of the central nervous system, the peripheral nervous system, the enteric nervous system, and the special senses. In the central nervous system, it is the astrocytes, oligodendrocytes, and microglia that safeguard nerve cell function and integrity that controls all behaviours and encompasses the cerebral cortex of the brain which is the root of humanity. In the peripheral nervous system, Schwann cells play the leading role, together with satellite glial cells of the sensory and autonomic ganglia, ensuring correct communication between the organs and tissues with the brain and the spinal cord. In the enteric nervous system, specialised enteric glial cells maintain all aspects of gastrointestinal function. Then there are distinctive glial cells of the special senses that ensure how the body perceives and reacts to its environment. In pathology, neuroglia strive to protect the diverse cellular components of the nervous system and are responsible for a proactive programme of posttraumatic restructuring that is aimed at recovery of life-sustaining function. Neuroglia: Function and Pathology provides a highly original and comprehensive account of the physiology and pathophysiology of glial cells in the central and peripheral nervous systems. The first part of the book provides a far-reaching description of glial cell form and function, from their evolution in invertebrates to their complexity in humans, encompassing the developmental origin of the varied glial cell types and their diversity of morphology, molecular biology and cellular physiology. The second part of the book is devoted to an all-embracing evaluation of glial cell pathophysiology, commencing with definitive explanations of the fundamental pathologies of the main glial cell types, and ending in a systematic examination of glial contributions to specific neurological diseases. This book emphasises the central roles played by the different classes of neuroglial cells in the progression and outcome of neurological disorders of the central and peripheral nervous systems and highlights potential of glial cells as therapeutic targets. The book contains more than 2500 key references from over 150 years of glial research and is superbly illustrated with over 350 original and explanatory full colour figures that describe the diverse characteristics and properties of glial cells in health and disease. Under the same cover, this book combines an authoritative reference book for research and clinical neuroscientists and at the same time serves as an instructive textbook for students of neuroscience, from undergraduates to postgraduates. Single volume covering key aspects of glial cell physiology and pathology In depth overview of the history of glial cell research Comprehensive review of glial cell physiology and pathology Authoritative special chapters on the major neurological diseases Full colour throughout, with 360 illustrations

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.
