In this article we will discuss about the role of PTH and Vit. D3 in calcium metabolism. Role of PTH in Calcium Metabolism: Hypocalcemia in blood stimulates parathyroid gland for PTH secretion. During calcium metabolism, it shows following functions— 1. On bones: Drop of Ca++ level in blood, stimulates PTH secretion. PTH uses bones as Ca++-bank from which it withdraws [...]
In this article we will discuss about complementary interactions between insulin and glucagon. Role of Insulin: Insulin influences carbohydrate metabolism mainly in the liver and muscles. The binding of insulin with the receptor protein may reduce intracellular cAMP in the target cells either by depressing the membrane bond adenylate cyclase or by stimulating the membrane associated phosphodiesterase that destroys cAMP. [...]
