Adrenal glands are called the ‘life-saving glands’ or ‘essential endocrine glands’. It is because the absence of adrenocortical hormones causes death within 3 to 15 days and absence of adrenomedullary hormones, drastically decreases the resistance to mental and physical stress. FUNCTIONAL ANATOMY OF ADRENAL GLANDS There are two adrenal glands. Each gland is situated on […]

Medulla is the inner part of adrenal gland and it forms 20% of the mass of adrenal gland. It is made up of interlacing cords of cells known as chromaffin cells. These cells contain fine granules which are stained brown by potassium dichromate. PLASMA LEVEL OF CATECHOLAMINES Adrenaline: 3 µg/dL Noradrenaline: 30 µg/dL Dopamine: 3.5 […]
