The rapidly advancing techniques of cell and molecular biology have intensified investigations of mechanisms responsible for detecting diminishing oxygen supply in the organism. In arterial blood, the arterial chemoreceptors initiate complex cardiopulmonary and endocrinological reflexes designed to stabilize oxygen content in the tissues. In a well-balanced blend of basic and applied science, this book includes current trends and major developments in the field of chemoreception, grouped into six sections: - Molecular and Ionic Mechanisms in Chemosensory Transduction - Content, Distribution, and Release of Putative Sensory Transmitters - Pharmacological Aspects of Arterial Chemoreception - Primary Afferent Neurons: Morphological and Functional Properties - Arterial Chemoreceptors and Homeostasis: Normal and Pathologic Studies - Oxygen-Sensing Capabilities by Ganglia, Paraganglia, and Other Tissues This book should provide the reader with a comprehensive and integrated source of information on the latest advances in this growing and exciting field of biomedical research. It is intended for physiologists, neurologists, and pharmacologists, as well as anatomists and clinicians involved with cardiovascular research. This volume represents the edited compilation of oral communications and posters presented at the 9th International Symposium on Arterial Chemoreceptors, Park City, Utah.
