Book excerpt: Although it is the defining organ of the Chordata, the notochord and its cells are one of the least understood vertebrate organs. This may be because large parts of the notochord are often replaced with cartilaginous or bony vertebral bodies. The presence of cartilage in the notochord raises questions about the evolutionary relationships between notochord cells and cartilage cells. This book integrates classical analytical studies with recent palaeontological, experimental, and molecular studies in both developmental and evolutionary contexts. For example, although the early signaling function of the notochord is conserved across the vertebrates, many will be surprised to find that the role of the notochord in vertebral body development in tetrapods is not the blueprint for all vertebrates. Recent studies on zebrafish and medaka embryos have uncovered the molecular mechanisms of a somite-independent notochord-driven segmentation process that establishes vertebral centra and intervertebral spaces. As this process is not restricted to teleosts, the authors have written a general discussion about the role of the notochord in vertebral formation. Modularity and segmentation of the vertebral column are related topics. Further overarching themes are the structure, function and fate of the notochord in adult vertebrates and notochord–cartilage relationships.

Available in PDF, EPUB and Kindle. Book excerpt: Although it is the defining organ of Chordates, the notochord is perhaps the least understood of vertebrate organs because it is usually considered a transient structure only present in early embryonic development. Most tetrapods replace the notochord with cartilaginous or bony vertebral bodies and remnants of the notochord persist as intra- or intervertebral spaces and intervertebral discs. The presence of cartilage in the notochord of some tetrapods raises further important questions on the evolutionary relationships between notochordal cells and cartilage cells. This book explores these patterns of relationships between the notochord and vertebral axial chondrogenesis.

Available in PDF, EPUB and Kindle. Book excerpt: Animal life, now and over the past half billion years, is incredibly diverse. Describing and understanding the evolution of this diversity of body plans - from vertebrates such as humans and fish to the numerous invertebrate groups including sponges, insects, molluscs, and the many groups of worms - is a major goal of evolutionary biology. In this book, a group of leading researchers adopt a modern, integrated approach to describe how current molecular genetic techniques and disciplines as diverse as palaeontology, embryology, and genomics have been combined, resulting in a dramatic renaissance in the study of animal evolution. The last decade has seen growing interest in evolutionary biology fuelled by a wealth of data from molecular biology. Modern phylogenies integrating evidence from molecules, embryological data, and morphology of living and fossil taxa provide a wide consensus of the major branching patterns of the tree of life; moreover, the links between phenotype and genotype are increasingly well understood. This has resulted in a reliable tree of relationships that has been widely accepted and has spawned numerous new and exciting questions that require a reassessment of the origins and radiation of animal life. The focus of this volume is at the level of major animal groups, the morphological innovations that define them, and the mechanisms of change to their embryology that have resulted in their evolution. Current research themes and future prospects are highlighted including phylogeny reconstruction, comparative developmental biology, the value of different sources of data and the importance of fossils, homology assessment, character evolution, phylogeny of major groups of animals, and genome evolution. These topics are integrated in the light of a 'new animal phylogeny', to provide fresh insights into the patterns and processes of animal evolution. Animal Evolution provides a timely and comprehensive statement of progress in the field for academic researchers requiring an authoritative, balanced and up-to-date overview of the topic. It is also intended for both upper level undergraduate and graduate students taking courses in animal evolution, molecular phylogenetics, evo-devo, comparative genomics and associated disciplines.

Download or read book Imaging of Bone Tumors and Tumor Like Lesions written by A. Mark Davies and published by Springer Science & Business Media. This book was released on 2009-08-21 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detection and characterization of bone tumors with imaging remains a big challenge for every radiologist notwithstanding the impressive progress achieved by the introduction of several new imaging modalities. Moreover, new concepts in surgical and oncological treatment of these lesions require from the radiologist appropriate and focused answers to the specifc questions asked by the referring physicians in order to choose the best therapeutic approach for the in- vidual patient. Tis comprehensive textbook describes in detail the possibilities and limits of all moda- ties, including MRI, CT, nuclear medicine and interventional radiological procedures, employed for the modern imaging of tumoral and tumor-like lesions of bone. Teir role in the diagnosis, surgical staging, biopsy and assessment of response to therapy is discussed in detail, covering all tumor subtypes as well as their specifc anatomical location.Well selected and technically imp- cable illustrations strongly enhance the didactic value of this work. I am very much indebted and grateful to the three editors: A. Mark Davies, Murali Sundaram and Steven L. J. James, world authorities in musculoskeletal radiology, for their superb scientifc achievement in preparing and editing this wonderful volume as well as for their individual ch- ters. I would also like to thank the large international group of collaborating authors, who are also widely acknowledged for their specifc expertise in the area of bone tumors, for their outstanding contributions.

Download or read book Hyman s Comparative Vertebrate Anatomy written by Libbie Henrietta Hyman and published by University of Chicago Press. This book was released on 1992-09-15 with total page 806 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book, now in its third edition, is to introduce the morphology of vertebrates in a context that emphasizes a comparison of structire and of the function of structural units. The comparative method involves the analysis of the history of structure in both developmental and evolutionary frameworks. The nature of adaptation is the key to this analysis. Adaptation of a species to its environment, as revealed by its structure, function, and reproductive success, is the product of mutation and natural selection–the process of evolution. The evolution of structure and function, then, is the theme of this book which presents, system by system, the evolution of structure and function of vertebrates. Each chapter presents the major evolutionary trends of an organ system, with instructions for laboratory exploration of these trends included so the student can integrate concept with example.

Book excerpt: Organ Culture provides information pertinent to the fundamental aspects of the study of autodifferentiation. This book discusses the physiological differentiation, the action of substances that inhibit or stimulate growth, and the interactions of associated organs. Organized into 10 chapters, this book begins with an overview of the differentiation of embryonic organs in natural media. This text then presents the study of differentiation in synthetic solid or liquid media and explains the biochemical and physiological requirements of the tissues. Other chapters consider the problems of sexual differentiation and intersexuality in vitro by providing a comparative study of avian and mammalian embryos. This book analyzes as well the interactions between hormones, inhibitor substances, and receptor organs in vitro. The final chapter deals with the study of organ chimeras in vitro and the related study of the organ culture of malignant tumors. This book is a valuable resource for embryologists and research workers.
