DEFINITION:
- adenohypophysis
-
The anterior lobe of the pituitary gland. It secretes growth hormone, fibroblast growth hormone, corticotropin, ß-endorphin, thyroid-stimulating hormone, follicle-stimulating hormone, luteinizing hormone, and prolactin; these are released or inhibited by the actions of the pituitary of hypophysiotropic factors secreted by the hypothalamus, and they regulate the functioning of the thyroid, gonads, adrenal cortex, and other endocrine organs. As a consequence, the hypothalamo-pituitary unit is of vital importance to the growth, maturation, and reproduction of the individual. The adenohypophysis comprises the pars tuberalis and the pars distalis (the main body of the adenohypophysis); the pars intermedia contains cells that secrete ß-endorphin, melanotropins, and other regulators but is sometimes considered to be part of the neurohypophysis. The adenohypophysis has its origin in the buccal epithelium of the embryo. Called also anterior pituitary.
