Abstract
The adenohypophyseal hormones influence general body growth and carbohydrate metabolism and exercise direct control on the functions of the adrenal cortex, the thyroid and the gonads. The six known hormones of the anterior pituitary are classified as metabolic and gonadotropic.
In describing the biologic properties and physicochemical characteristics of the various anterior pituitary hormones, the author discusses such topics as the hormonal mechanism governing mammary growth and lactation, differentiation of ovine prolactin and bovine prolactin, and the physicochemical differences among the growth hormones, luteinizing hormones and adrenocorticotropins isolated from the pituitary glands of various species.
