Rathke's pouch is an upgrowth from the roof of the embryo stomodium that contributes to the adenohypophysis of the pituitary or hypophysis. The pouch contains ectoderm as it is located cranial to the buccopharyngeal (oropharyngeal or oral) membrane. The neurohypophysis is from a simultaneous downgrowth from the developing diencephalon.
