The pituitary gland is a central regulator of growth, reproduction, and endocrine physiology and functions to relay signals from the hypothalamus to various target organs.
WebThe anterior pituitary originates from the digestive tract in the embryo and migrates toward the brain during fetal development. There are three regions: the pars distalis is the most anterior, the pars intermedia is adjacent to the posterior pituitary, and the pars tuberalis is a slender “tube” that wraps the infundibulum. WebThe ontogenesis of the pituitary gland is considered from anatomical and functional points of view.
