Adenohypophysis
Definition
The anterior and intermediate lobe of the hypophysis (pituitary gland), possessing an epithelial-glandular structure distinct from the neurohypophysis; it is responsible for the synthesis and secretion of most essential trophic hormones, such as growth hormone (GH), prolactin, ACTH, TSH, LH, and FSH. This structural component regulates the metabolic activity and homeostasis of the entire endocrine system through complex feedback mechanisms.
