Glucocorticoids stimulate, gluconeogenesis, lipolysis and proteolysis, and inhibit cellular uptake and utilisation of amino acids.Ĭortisol is also involved in maintaining the cordiovasular system as well as the kidneyt functions. Β - mineralocorticoids - regulate the balance of water and electrolytes in our boyd.Īldosterone is the main mineral corticoid in our body. Α - glucocorticoids - involved in carbohydrate metablism. The adrenal cortex secretes many hrmones, commonly called as corticoids. The adrenal cortex can be divided into 3 layers, called zona glomerulose (outer layer), zone fasciculate (middle layer) and zona reticularis (inner layer). They also stimulate the break down of lipids and proteins. sweating etc.īoth the hormones increase the heart beat, the strength of heart contraction and the rate of respiration.Ĭatecholamines also stimulate the breakdown of glycogen resulting in an increased concentration of glucose in blood. These hormones increase alertness, pupillary dilation, piloerection (raising of hairs). They are called emergency hormones or hormones of fight or flight. These are commonly called as catecholamines.Īdrenaline and nor-adrenaline are rapidly secreted in response to stress of any kind and during emergency situations. The adrenal medulla secretes two hormones called adrenaline or epinephrine and nor-adrenaline or norepinephrine. The centrally located tissue is called the adrenal medulla and outside this lies the adrenal cortex. The gland is composed of two types of tissues. Location : Our body has one pair of adrenal glands, one at the anterior part of each kidney.
