Endocrine Glands
and Hormones
In the remainder of this section we describe some of the best understood and most important of vertebrate hormones. While the following discussion is limited principally to a brief overview of mammalian hormonal mechanisms (since laboratory mammals and humans have always been the objects of the most intensive research), we will point out some important differences in functional roles of hormones among different vertebrate groups.
