Histogenesis of Pituitary gland in prenatal sheep (Ovis aries)

Abstract

The pituitary is a master endocrine gland involved in homeostasis and regulation of growth, reproduction, sexual maturation, pregnancy, metabolism, lactation, and stress responses. Present study on pituitary gland of prenatal sheep revealed that in group I, Rathke's pouch formation was seen at 25 days of gestation. In group II, at 55 days of gestation, in pars distalis cells were differentiated into chromophils and chromophobes, at 85 days of gestation chromophils were differentiated into acidophils and basophils. In group
III, the number of cells and capillaries were increased.
