The walls of the diverticulum develop into the anterior lobe of the pituitary gland. [TFD][VHOG] FMA:302929 pouch of Rathke SCTID:362583008 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] XAO:0000430 NCIT:C54098 adenohypophysial pouch UMLS:C0229548 UBERON:0005356 UMLS:C1709841 Rathke's cyst Rathke's pocket AAO:0011094 hypophyseal pouch VHOG:0000674 hypophyseal diverticulum NCIT:C34281 nasohypophyseal pouch A pouch of ectoderm that grows out from the upper surface of the embryonic stomodeum and gives rise to the anterior and intermediate lobes of the pituitary gland[MP]. In embryogenesis, Rathke's pouch is a depression in the roof of the developing mouth in front of the buccopharyngeal membrane. It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system[WP]. SCTID:61127000 neuronames:1516 EHDAA2 distinguishes between the adenohypophyseal pouch and it's precursor Rathke's pouch epithelium. Rathkes pouch epithelium Rathke's cleft median funnel­-shaped invagination of ectoderm, the nasohypophyseal pouch.
