Adenohypophysis

Adenohypophysis (adenohypophysis, pna, lnh; adeno- + pituitary gland; syn. anterior pituitary gland) - the anterior lobe of the pituitary gland, which develops from the ectoderm of the oral region of the embryo and consists mainly of epithelial cells that produce hormones. The adenohypophysis makes up about 75% of the mass of the pituitary gland and includes 3 main types of secretory cells: somatotropocytes, which synthesize growth hormone; corticotropocytes that synthesize adrenocorticotropic hormone; and thyrotropocytes, which synthesize thyroid-stimulating hormone. Hormones of the adenohypophysis regulate the functions of the thyroid gland, adrenal glands, gonads and growth. The adenohypophysis is under the control of the hypothalamus, which regulates the secretion of hormones through the portal vascular system.

The adenohypophysis is an endocrine gland located in the brain. It consists of two sections - adenocytes and hypocytes. The adenohypophysium is located in the hypothalamus, between the pituitary gland and the midbrain. The gland has one large hole, which is the entrance to
