This textbook of basic endocrinology has been used widely in medical schools as well as graduate and undergraduate programs. It covers not only physiology, but anatomy, biochemistry, and cell and molecular biology. It provides a solid, clear, succinct account of basic endocrine function with pathophysiological and clinical correlations. A new chapter on 'Cytokines and Immune-Endocrine Interactions" has been added to the third edition. In addition, the chapter on growth has been completely rewritten. All other chapters have been updated and twenty-five new figures have been added.
