The Embryohormonic Relations of the Pituitary Gland to Mesenchymal Tissues

Abstract

The control which the pituitary exercises over the tissues of mesenchymal origin is no less striking than that which the thyroid exercises over the ectoderm. Examples of hypo- and hyper-function of the pituitary are given showing the selective action. Obvious relations exist between the pituitary and mesenchymal tissues: the bone, cartilage, fat, smooth muscle, renal cells, blood vessels. The relationship of the pituitary to the suprarenal cortex is emphasized.
