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] SCTID:245534008 pars intermedia adenohypophysis pars intermedia adenohypophyseos pars intermedia (glandula pituitaria) pars intermedia of anterior lobe of pituitary gland The thin boundary between the adenohypophysis and neurohypophysis of the pituitary that produces melanocyte stimulating hormone (MSH); this area is small or absent in mammalian adults.
