where is the thymus located in your body
Thymus In children, the thymus is pinkish-gray, soft, and lobulated on its surfaces. At birth it is about 4–6 cm long, 2.5–5 cm wide, and about 1 cm thick.[1] It is made up of two lobes that meet in upper midline, that stretch from below the thyroid in the neck to as low as the cartilage of the fourth rib.[1] It lies beneath the sternum, rests on the pericardium, and is separated from the aortic arch and great vessels by a layer of fascia. The left brachiocephalic vein may even be embedded within the thymus.[1] In the neck, it lies on the front and sides of the trachea, behind the sternohyoidei and sternothyreoidei.[1]
