Thymus Gland

Thymus Gland                                                

   It is a roughly triangular, bilobed gland. It is located in the mediastinum (ie., between the lungs). It lies between the sternum and the pericardium. Its size varies with age. It is largest in the early part of life (upto 15 years). At birth it weighs 10 - 15 g. After puberty it greatly decreases in size. Each thymus lobe is surrounded by a thin capsule made of the connective tissue. It has 2 layers. The inner layer is the medulla, the outer layer is cortex. The lymphocytes are found only in cortex layer.
