adenohypophysis

Go to external page http://purl.obolibrary.org/obo/UBERON_0002196

The glandular, anterior lobe of the pituitary gland. The anterior pituitary regulates several physiological processes including stress, growth, and reproduction[WP]. 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[ZFA].

external 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 mamalian vertebrates, the adenohypophysis remains in a subepithelial position and there exists no equivalent of Rathke's pouch in zebrafish. Herzog et al, 2004.[TAO]

Region of the pituitary gland derived from the buccal protrusion consisting of three regions.[AAO]

homology notes

It (the hypophysis) develops embryonically in all vertebrates from two ectodermal evaginations that meet and unite. An infundibulum grows ventrally from the diencephalon of the brain, and Rathke's pouch extends dorsally from the roof of the developing mouth, or stomodaeum. The infundibulum remains connected to the floor of the diencephalon, which becomes the hypothalamus, and gives rise to the part of the gland known as the neurohypophysis. (...) Rathke's pouch loses its connection with the stomodaeum in most adult vertebrates and gives rise to the rest of the gland, the adenohypophysis. (...) A well-developed hypophyseal system with functional connections to the hypothalamus is unique to craniates.[well established][VHOG]

taxon notes

In contrast to mammalian vertebrates, the adenohypophysis remains in a subepithelial position and there exists no equivalent of Rathke's pouch in zebrafish

While in most basal fish and tetrapods the adenohypophyseal anlagen invaginates to form Rathke's pouch, in teleost fish the adenohypophyseal placode does not invaginate but rather maintains its initial organization forming a solid structure in the head[NCBIBook:NBK53175].
