<prompt> Rathkes pouch is related to the development of ?Posterior pituitaryNeurohypophysisAdenohypophysisNone of the above  <response>: Ans. is c i.e., AdenohypophysisPITUITARY GLAND HYPOPHYSIS CEREBRIPituitary gland lies within hypophysealpituitary fossa or sella turcica of sphenoid bone which is roofed by diaphragm sellae. It is suspended from tuber cinereum of hypothalamus by infundibulum pituitary stalk. It is related anterosuperiorly to optic chiasma, laterally to cavernous sinus and inferiorly to sphenoid air sinuses in the body of sphenoid. Pituitary gland is oval in shape, measures 8 x12 mm, and weighs about 500 mg. Pituitary gland has two main subdivisions:- i Adenohypophysis anterior lobe, and ii Neurohypophysis posterior lobe.Adenohypophysis anterior lobe include :- i pars anterior or pars distalis or pars glandularis or anterior lobe proper, ii pars intermedia intermediate lobe; and iii tuberal lobe pars tuberalis. It develops from an upward growth Rathkes pouch from the ectodermal roof of stomodeum.Neurohypophysis posterior lobe include i pars posterior or pars nervosa or neural lobe or posterior lobe proper; ii infundibulum infundibular stem; and iii median eminence. It develops from a downgrowth from the 3 ventriclediencephalon neuroectoderm called infundibulum.Anterior lobe contains many hormone secreting cells: chromophils acidophils, basophils, chromophobes and follicullostellate cells. Posterior pituitary contain neuroglia like pituicytes which do not secrete any hormone. The posterior pituitary hormones ADH and oxytocin are synthesized in hypothalamus and transpoed to posterior lobe by hypothalamohypophyseal nerve fiber tract and stored in the axon terminals of neurohypophysis in Herring bodies before their release.
