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.

Over the last few years there have been huge advances made in our understanding of the interactions between the brain and the gut – the enteric nervous system. This book is particularly relevant in the understanding, diagnosis and management of irritable bowel syndrome – the most common functional disorder of the bowel. IBS has been diagnosed in 10-20% of adults in the US, and symptoms of IBS are responsible for more than 3 million visits to the physician in the US. This book is aimed at specialist gastroenterologists but also should be of interest for trainees and fellows in gastroenterology, as well as PCPs and GPs with an interest in this subject.

Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

This book first presents an overview on the chemical coding of the morphological neuron types described by Stach in the pig intestine. In doing so, we have pointed out the difference between the definitions of type I neurons given by Dogiel and Stach. Secondly, it provides a basis for the morpho-chemical classification of human enteric neurons as revealed by their immunoreactivity for neurofilaments and several neuroactive substances or related markers.

In this new release, a selection of 44 essential topics in each major organ system is defined, then major themes, concept and principles surrounding these words in their physiologic scenarios are elaborated. For each keyword, a question is posed at the end of the text to test for a better understanding of the associated physiology of nervous and gastrointestinal systems. This book presents an easy reference guide for those just starting out in the area of physiology and for those who are interested in clear and succinct definitions of key terms.

FROM THE PREFACE:The original purpose of the First Edition of Physiology of the Gastrointestinal Tractto collect in one set of volumes the most current and comprehensive knowledge in our fieldwas also the driving force for the Fourth Edition. The explosion of information at the cellular level, made possible in part by the continued emergence of powerful molecular and cellular techniques, has resulted in a greater degree of revision than that of any other edition. The first section, now titled "Basic Cell Physiology and Growth of the Gl Tract" contains numerous new chapters on topics such as transcriptional regulation, signaling networks in development, apoptosis, and mechanisms in malignancies. Most of the chapters in this section were edited by Juanita L. Merchant. Section II has been renamed "Neural Gastroenterology and Motility" and has been expanded from seven chapters with rather classic titles to more than twenty chapters encompassing not only the movement of the various parts of the digestive tract but also cell physiology, neural regulation, stress, and the regulation of food intake. Almost all of the chapters were recruited and edited by Jackie D. Wood. The third section is entirely new and contains chapters on "Immunology and Inflammation" which were edited by Kim E. Barrett. The fourth section on the "Physiology of Secretion" consists of chapters with familiar titles, but with completely updated information to reflect the advances in our understanding of the cellular processes involved in secretion. The last section on "Digestion and Absorption" contains new chapters on the intestinal barrier, protein sorting and ion channels along with those focusing on the uptake of specific nutrients. These chapters were recruited and edited by Hamid M. Said and Fayez K. Ghishan.· Collected in one set - the most current and comprehensive coverage of gastrointestinal physiology· Information presented in a style that is both readable and understandable· Valuable to the specialized researcher, the clinical gastroenterologist, the teacher, and the student· Features an entirely new section on Immunology and Inflammation· Each section edited by the preeminent scientist in the field

In their second year in medical school, students begin to learn about the differences between "disease" and "illness." In their studies of pathology they learn to understand disease as pertubations of molecular biological events. And we clinicians can show disease to them by our scans, lay it out even on our genetic scrolls, and sometimes even point out the errant nucleotide. Disease satisfies them and us; at Yale, lectures on the gastrointestinal tract run from achalasia to proctitis. There is, alas, little mention of functional bowel disease or of the irritable or spastic colon, for that is not easy to show on hard copy. Functional bowel disease represents "illness," the response of the person to distress, to food, to the environment, and to the existential problems of living. In real life such matters are most important. Richard Cabot first found out at the Massachusetts General Hospital almost a century ago that 50% of the patients attending the outpatient clinic had "functional" complaints. The figure had grown to over 80% when the very same question was reexamined 60 years later.
