Özet
The thymus gland is a lymphoepithelial organ located in the anterosuperior mediastinum. It develops from the third pharyngeal cleft in the sixth week of pregnancy, and the development continues until the ninth week. The thymus plays a role in the maturation of the T cell. It is an endocrine gland. It takes part in the regulation of the immune system starting from the fetal period. Its approximate weight is 10–15 g during the neonatal period, and it reaches 30–40 g in puberty. Blood is supplied by the internal thoracic artery and the inferior thyroid artery. Venous return is provided by the thymic veins draining into the brachiocephalic vein, internal thoracic vein, and the inferior thyroid vein (Fig. 1). It receives sympathetic fibers from the cervicothoracic ganglion and the subclavian loop and parasympathetic fibers from the vagus nerve. The fibers of the phrenic nerve supply sensation from the capsule of the gland [1].
