The revised, updated second edition of this text incorporates the past five years" discoveries on cellular and molecular processes involved in hormone production and action. Dr. Goodman integrates these advances into a systematic review of the organization of the endocrine system, the functions of individual endocrine glands, and the complex hormonal interactions that govern sodium and water balance, calcium homeostasis, fuel metabolism, reproduction, growth, and development. This timely information on normal endocrine physiology should prepare the student to study not only endocrine diseases, but also the cellular and molecular disturbances that disrupt normal function and require rational therapy.
