Abstract
The thymus, along with the lower pair of parathyroid glands, is derived from the third and fourth pharyngeal pouches. The right and left halves of the gland fuse to form a pyramidal-shaped organ enclosed by a thin fibrous capsule. The thymus has a vital location adjacent to the important organs of the mediastinum. The gland usually sits in the anterosuperior portion of the mediastinum, with the base of the thymus sitting on the pericardium and the upper poles of each lobe extending superiorly into the neck.
