Thymus. The thymus is a lymphoid gland comprised of two identically sized lobes, located behind the sternum (breastbone) but in front of the heart. It derives its name from a resemblance it bears to the bud of the thyme plant (thymus in Latin). At puberty, the thymus reaches the height of its use, becoming its largest.
The thymus has 3 main layers: 1  The medulla is the innermost part of the thymus. 2  The cortex is the layer surrounding the medulla. 3  The capsule is the thin covering over the outside of the thymus.
