Name: adenohypophysis
Synonyms: anterior hypophysis, anterior pituitary
Definition: The anterior lobe of the hypophysis (pituitary gland). This lobe contains cells that produce prolactin, growth hormone, thyroid-stimulating hormone, follicle-stimulating hormone and proopiomelanocortin. In contrast to mammalian vertebrates, the adenohypophysis remains in a subepithelial position and there exists no equivalent of Rathke's pouch in zebrafish.

Name: secretory granule
Synonyms: secretory vesicle
Definition: A small subcellular vesicle, surrounded by a membrane, that is formed from the Golgi apparatus and contains a highly concentrated protein destined for secretion. Secretory granules move towards the periphery of the cell and upon stimulation, their membranes fuse with the cell membrane, and their protein load is exteriorized. Processing of the contained protein may take place in secretory granules.
