(ii) Ovulation : Luetinizing Hormone (LH) secreted by anterior pituitary (adenolypophysis) regulates the ovulation. (iii) Rise in blood sugar : Insulin secreted by Islets of Langerhans regulate rise in blood sugar. (iv) Fall in calcium ion level in blood : Parathormone secreted by parathyroid gland regulate rise in blood sugar. (v) Urinary elimination of water : ADH secreted by posterior pituitary (neurohypophysis) is called vasopressin. It decreases the volume of water by increasing reabsorption from urine.
