Download or read book Colonic Motility written by Sushil K. Sarna and published by Biota Publishing. This book was released on 2010-11-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Human Anatomy Volume Ii Abdomen And Lower Limb written by A. Halim and published by I. K. International Pvt Ltd. This book was released on 2008-01-31 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volumes endeavour to integrate different subdivisions of anatomy to enable students of anatomy to learn all the relevant aspects of a topic like osteology, soft parts, development and clinical application at the same time. It is a common knowledge that bone carries our anatomy and forms its central part. As such, each topic begins with a brief description of the skeletal framework of the region followed by the description of the surrounding soft parts. The study of soft parts does not merely lie in parroting of relations of structures but it essentially relies on visualization of parts and regions based on dissection and diagrams. Anatomy, if not understood in its proper perspective and only memorised in parts, tends to be forgotten. Anatomy per se is a visual science and the best methods of visual recall of structural interrelationship are simple diagrams. Line diagrams which can be easily reproduced constitute an important feature of the book. Besides, this book is profusely illustrated. Every mutual relationship of soft structures has been explained by well-placed diagrams. It is widely recognised that anatomy can be made interesting, easy to understand and assimilate by dealing with its clinical application. At the end of each topic under the heading Clinical Application, close relationships existing between the regional anatomy and clinical medicine are explained. Thus, the book is meant to be very useful to the students during their clinical years also. It is hoped that the book will be highly useful for students of M.B.B.S.
