Histogenesis of suprarenal gland

Abstract               Histogenesis of suprarenal gland (right and left) was studied in 30 human fetuses of different gestational age using routine Hematoxyline and Eosine staining in department of Anatomy M.G.M. Medical College and Hospital, Aurangabad. It was observed that suprarenal gland has superficial zone of darkly stained cells beneath the capsule which is permanent cortex. Deeper light zone called fetal cortex. Changes were seen in capsule, cortex and medulla. Thickness of capsule was increased as age advances. The arrangement of permanent cortex changed from discrete cells and clusters to well formed glomerulus as gestational age advances. There was decrease in thickness of fetal cortex with gestational age. As gestational age increases sinusoidal cells and ganglionic cells in medulla increase.
