Download or read book The Sliding Filament Theory of Muscle Contraction written by David Aitchison Smith and published by Springer. This book was released on 2019-02-05 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the molecular mechanism of muscle contraction started with the discovery that striated muscle is composed of interdigitating filaments which slide against each other. Sliding filaments and the working-stroke mechanism provide the framework for individual myosin motors to act in parallel, generating tension and loaded shortening with an efficient use of chemical energy. Our knowledge of this exquisitely structured molecular machine has exploded in the last four decades, thanks to a bewildering array of techniques for studying intact muscle, muscle fibres, myofibrils and single myosin molecules. After reviewing the mechanical and biochemical background, this monograph shows how old and new experimental discoveries can be modelled, interpreted and incorporated into a coherent mathematical theory of contractility at the molecular level. The theory is applied to steady-state and transient phenomena in muscle fibres, wing-beat oscillations in insect flight muscle, motility assays and single-molecule experiments with optical trapping. Such a synthesis addresses major issues, most notably whether a single myosin motor is driven by a working stroke or a ratchet mechanism, how the working stroke is coupled to phosphate release, and whether one cycle of attachment is driven by the hydrolysis of one molecule of ATP. Ways in which the theory can be extended are explored in appendices. A separate theory is required for the cooperative regulation of muscle by calcium via tropomyosin and troponin on actin filaments. The book reviews the evolution of models for actin-based regulation, culminating in a model motivated by cryo-EM studies where tropomyosin protomers are linked to form a continuous flexible chain. It also explores muscle behaviour as a function of calcium level, including emergent phenomena such as spontaneous oscillatory contractions and direct myosin regulation by its regulatory light chains. Contraction models can be extended to all levels of calcium-activation by embedding them in a cooperative theory of thin-filament regulation, and a method for achieving this grand synthesis is proposed. Dr. David Aitchison Smith is a theoretical physicist with thirty years of research experience in modelling muscle contractility, in collaboration with experimental groups in different laboratories.

Download or read book Muscle Biology written by Bruce M. Carlson and published by Academic Press. This book was released on 2021-11-28 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Muscle Biology: The Life History of a Muscle looks at the story of a muscle from its embryonic beginnings, through its growth and ability to adapt to changing functional circumstances during adult life, to its eventual decline in both structure and function as old age progresses. Injury occurs to muscle during normal activity, after trauma, and during the source of certain diseases. Chapters on both muscle regeneration and muscle diseases emphasize the possibilities and limitsations of the healing capacity of muscle fibers. Muscle Biology begins with a brief review about the structure and function of a normal mature muscle and then proceeds to follow the developmental history of a muscle from the embryo to old age in a manner that gives the reader a perspective about not only developmental controls but also how at any stage of development a muscle is able to adapt to its functional environment. The book discusses both normal and abnormal changes in the muscle, the mechanisms behind those changes and how to mitigate deleterious changes from disease, 'normal' aging, and disuse/lack of physical activity. This is a must-have reference for students, researchers and practitioners in need of a comprehensive overview of muscle biology. Provides an overview of muscle biology over the course of one’s entire lifespan Explains the important elements of each aspect of muscle biology without drowning the reader in excessive detail Contains over 300 illustrations and includes chapter summaries
Download or read book Nerve Muscle Interaction written by Gerta Vrbova and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second century, Galen recognized that nerve and muscle were functionally inseparable since contraction of muscle occurred only if the nerves supplying that muscle were intact. He therefore concluded that the shortening of a muscle was controlled by the central nervous sytem while the extension of a muscle could occur in the absence of innervation. Nerves, he thought, were the means of transport for animal spirits to the muscles; the way in which animal spirits may bring about contraction dominated the study of muscle physiology from that time until the historical discovery of Galvani that muscle could be stimulated electrically and that nerve and muscle were themselves a source of electrical energy. It is now well known that nerves conduct electrically and that transmission from nerve to striated muscle is mediated by the chemical which is liberated from nerve terminals onto the muscle membrane. In vertebrates this chemical is acetylcholine (ACh). Thus the concept of spirits that are released from nerves and control muscle contraction directly, is no longer tenable. Nevertheless the concept of 'substances' transported down nerv~s which directly control many aspects of muscle has not been abandoned, and has in fact been frequently reinvoked to account for the long-term regula tion of many characteristics of muscle (see review by Gutmann, 1976) and for the maintenance of its structural integrity.

Download or read book Scaling in Biology written by James H. Brown and published by Oxford University Press, USA. This book was released on 2000 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scaling relationships have been a persistent theme in biology at least since the time of Leonardo da Vinci and Galileo. While there have been many excellent empirical and theoretical investigations, there has been little attempt to synthesize this diverse but interrelated area of biology. In an effort to fill this void, Scaling in Biology, the first general treatment of scaling in biology in over 15 years, covers a broad spectrum of the most relevant topics in a series of chapters written by experts in the field. Some of those topics discussed include allometry and fractal structure, branching of vascular systems of mammals and plants, biomechanical and life history of plants, invertebrates and vertebrates, and species-area patterns of biological diversity.

Download or read book Optical Microendoscopy for Imaging Cells Lying Deep Within Live Tissue written by Robert Juson Barretto and published by Stanford University. This book was released on 2010 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical microendoscopy is an emerging modality for imaging in live subjects. Using gradient refractive index (GRIN) microlenses, microendoscopy enables subcellular-resolution imaging in deep tissues that are inaccessible by traditional imaging techniques. We present a platform of methods and technologies that build upon GRIN microendoscopy: 1) miniaturized microscopes for imaging in awake, behaving animals, 2) methods for imaging contractile dynamics in the muscles of animal and human subjects, 3) chronic brain preparations that allow for longitudinal examinations of subcellular neuronal features and disease progression, and 4) novel microendoscope probes whose imaging capabilities approach that of standard water-immersion microscope objectives. When combined with the broad sets of available fluorescent reporters, and minimally invasive surgical preparations, the work described in this dissertation enables sophisticated experimental designs for probing how cellular char- acteristics may underlie or explain behavior, in models of both healthy and diseased states.
