Abstract

The terms hypophysis and pituitary are used loosely and interchangeably by many if not most writers on endocrine organs. By "pituitary" the writers of this paper understand an assemblage of two diverse elements: an epithelial hypophysis derived from the buccal ectoderm of the embryo and a pars nervosa originating from the infundibulum of the brain. The junction and fusion of these two parts form the pituitary proper. It is with such an interpretation that we shall use the terms hypophysis and pituitary.
