Martin Heinrich Rathke first described in [[1839]] the embryonic structure, now known as [[Rathke pouch]], from which the anterior lobe of the [[pituitary gland]] develops
((Ueber die Entstehung der Glandula pituitaria. Archiv für Anatomie, Physiologie und wissenschaftliche Medicin, Berlin, 1838: 482-485.))

Also known as [[hypophyseal diverticulum]], is an ectodermal outpouching of stomodeum (primitive oral cavity lined by ectoderm) which forms at approximately 3-4 weeks gestation and goes on to form the [[adenohypophysis]] of the [[pituitary gland]].

Craniopharyngiomas frequently grow from remnants of the [[Rathke pouch]], which is located on the cisternal surface of the [[hypothalamic region]]. These lesions can also extend elsewhere in the infundibulohypophyseal axis.
