B Rathke pouchRef: Hypothalamic-pituitary Development: Genetic and Clinical Aspect, pg. 2-3 The anterior pituitary and intermediate lobe of pituitary develops from Rathkes pouch, which is initially derived from the anterior neural ridge, adjacent to cells in the neural plate. Neural plate contributes to ventral diencephalon. Posterior lobe of pituitary develops from the infundibulum, an evagination of the ventral diencephalon.
