Written at a level accessible to the layperson by a well-known endocrinologist and a medical writer, this authoritative volume contains more than 250 alphabetically arranged entries that range in length from a few sentences to several pages.The goal of this reference is to give a broad overview of the normal and abnormal function of the endocrine system. A useful 13-page introduction provides general information on the functioning of the endocrine system over the human life span as well as a summary of the function of each of the glands.
