This volume is intended to cover research in the field of muscle morphology since publication of the previous edition by Haggquist in 1956. The development of new techniques, coupled with an intensified interest in muscle, has resulted in a vast literature which no single person could review, especially within the limitations of one volume. When I accepted the flattering offer to write a new edition, I quickly abandoned any hope of a comprehensive review. Instead, I tried to consider, within my limits, those lines of research which I believe to be important for the understanding of mammalian and ultimately human muscles under normal, experimental, and pathological conditions. It would be naive to suggest that muscle can be adequately described in purely morphologi cal aspects; I would characterize the results of my effort as "muscle as seen with the eyes of a morphologist". It gives me pleasure to acknowledge the help of several colleagues who read and commented on drafts of individual chapters: Dr. Brenda Eisenberg, Chicago; Dr. Else Nygaard, Copenhagen; Dr. Stefano Schiaffino, Padova; Dr. Michael Sjostrom, Umea; Dr. Lars~Erik Thornell, Umea. None of these individ uals can be held responsible for any error or obscurity that persists. Indeed, without their assistance there would have been more. I also thank those col leagues who allowed me to include their published and unpublished material; their names, and also those of the publishers who kindly granted copyright permission, are given in the individual figure captions.

Histologically, muscle is conveniently divided into two groups, striated and nonstriated, based on whether the cells exhibit cross-striations in the light microscope (Figure 3). Smooth muscle is involuntary: its contraction is controlled by the autonomic nervous system. Striated muscle includes both cardiac (involuntary) and skeletal (voluntary). The former is innervated by visceral efferent fibers of the autonomic nervous system, whereas the latter is innervated by somatic efferent fibers, most of which have their cell bodies in the ventral, motor horn of the spinal cord. Smooth muscle is designed to have slow, relatively sustained contractions, while striated muscle contracts rapidly and usually phasically. Both cardiac and smooth muscle cells are mononucleated, whereas skeletal muscle cells (fibers) are multinucleated. [In aging hearts or hypertrophied hearts, cardiac muscle cells are often binucleated.] Multinucleation of skeletal muscle arises during development by the cytoplasmic fusion of muscle precursor cells, myoblasts. Adult skeletal muscle cells do not divide; that is also true of most cardiac myocytes. However, skeletal muscle exhibits a considerable amount of regeneration after injury. This is because adult skeletal muscle contains a stem cell, the satellite cell, which lies beneath the basement membrane surrounding the muscle fibers. [The multinucleation of cardiac muscle arises from karyokinesis without cytokinesis.] A diagrammatic series of enlargements of skeletal muscle are shown in Figure 4. A bundle of muscle fibers (fasciculus) is cut from the deltoid muscle. Each muscle cell is termed a myofiber or muscle fiber. Each muscle fiber contains contractile organelles termed myofibrils, which contain the contractile units of muscle termed sarcomeres. The sarcomeres are composed of myofilaments, which in turn are composed of contractile proteins. Muscle connective tissue layers are organized in concentric layers that are important in the entry and exit of vessels and nerves to and from the tissue. These are shown in Figure 5. The outermost layer is the epimysium or muscle sheath. Connective tissue septae (perimysium) run radially into the muscle tissue, dividing it into muscle fascicles. The deepest layer, surrounding each of the muscle fibers is the endomysium. The endomysium is in direct contact with a basal lamina that ensheathes each muscle fiber. It surrounds the plasma membrane of the muscle fiber termed the sarcolemma.

This volume presents for the first time the most up-to-date research findings in the field. Skeletal muscle consumes significant amounts of oxygen, and its oxygen flux increases significantly under conditions of exercise and muscle contraction. This makes the muscle vulnerable to oxidative stress, as concomitantly with the increase of oxygen flow there is an increase of oxygen free radicals, which are a byproduct of muscle respiration. A number of studies in the last decade have documented the involvement of oxygen free radicals in exercising muscles. The consequences of muscle oxidative stress have resulted mainly in increased muscle protein oxidation, elevation of lipid peroxidation, and depletion of muscle antioxidants. The mechanisms of this oxidative stress are under extensive investigation in laboratories around the world and are topics of the chapters in this volume. Understanding these mechanisms may help to improve the well-being and function of muscles in various physiological conditions, in muscle pathologies, and in tissue-ageing. This book is intended for professionals who are interested in muscle function, physiology, pathophysiology and well-being, such as therapists, trainers and medical professionals as well as for researchers in the field of muscle physiology.

Motility is a fundamental property of living systems, from the cytoplasmic streaming of unicellular organisms to the most highly differentiated and de veloped contractile system of higher organisms, striated muscle. Although of motility have a long and in scientific investigations into the mechanisms teresting history, the knowledge of molecular processes, especially in the area of regulation of control of motility, has been developing at an ever more rapid pace with the utilization of multidisciplinary approaches from physiology, cell biology, genetics, biochemistry, pharmacology, and biophysics. In Volume 3, Cell and Muscle Motility continues the same philosophy as that of the preceding volumes. The essays are meant to focus on topics of current interest, to be critical rather than exhaustive, and to indicate the current trends of research efforts. The series is intended to foster an in terchange of concepts among various workers in a variety of disciplines and to serve as a reference for students and workers who wish to familiarize them selves with the most current progress in motility.

Growth Associated Protein 43 (GAP-43), isolated from rat brain and considered a neuronal marker, is involved in neurite branching, cytoskeleton remodelling, neuronal development and protection. However, GAP-43 mRNA was found in embryonic chicken cells positive to meromyosin, as well as in human satellite cells, myoblasts and myotubes deriving from healthy or dystrophic muscles. Despite these findings, there is no clear evidence about its localization or relationship with other muscle proteins. The aim of this study was to investigate GAP-43 protein expression and localization in C2C12 cells and mice skeletal muscle fibers, using immunoblot and immunofluorescence protocols for confocal mycroscopy. Immunoblot analyses show the presence of GAP-43 in C2C12 cell homogenates as well as in mature muscle fibers. Immunofluorescent images reveal that the protein is localized nearby the external nuclear membranes in C2C12 myoblasts, while in C2C12 myotubes, it has been detected on muscular streaks, in a regular double strand pattern. This localization has been found also in Extensor Digitorum Longus fibers isolated from 1 week, 1 and 24 months old mice. In isolated adult mouse fibers, GAP-43 localization appears to be in relationship with crucial proteins such as triadin, alfa-actinin, RyR, DHPR, as well as mitochondria. In addition, cross-specimen analyses on skeletal muscle cells and mature fibers from Xenopus Laevis (amphibian), rat and human were performed, in order to interpret the results from an evolutionary point of view. In conclusion, these preliminary data confirm the presence of GAP-43 in all the analyzed skeletal muscles, and its localization supports the hypothesis of a possible new functional role in the muscle excitation-contraction coupling process.

It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.
