1. Rathke's pouch is a depression in the roof of the developing mouth in front of the buccopharyngeal membrane.
2. The pouch is a derivative of surface ectoderm& eventually loses its connection with the pharynx giving rise to the anterior pituitary (Adenohypophysis).
3. The anterior wall of Rathke's pouch proliferates; filling most of the pouch to form pars distalis and pars tuberalis. The posterior wall forms pars intermedia.
4. Sometimes, Rathke’s pouch persists as craniopharyngioma
