Above, the fibrous pericardium not only blends with the external coats of the great vessels, but is continuous with the pretracheal layer of the deep cervical fascia.
The lateral or superficial surface is convex, and covered by the skin, the superficial and deep fasciæ, the Sternocleidomastoideus, the superior belly of the Omohyoideus, the Sternohyoideus and Sternothyreoideus, and beneath the last muscle by the pretracheal layer of the deep fascia, which forms a capsule for the gland.
The lymphatic vessels of the thyroid gland consist of two sets, an upper, which accompanies the superior thyroid artery and enters the superior deep cervical glands, and a lower, which runs partly to the pretracheal glands and partly to the small paratracheal glands which accompany the recurrent nerves.
They may be divided into (a) a superficial set, placed on the anterior jugular vein; (b) a deeper set, which is further subdivided into prelaryngeal, on the middle cricothyroid ligament, and pretracheal, on the front of the trachea.
Of the lower set, some pierce the conus elasticus and join the pretracheal and prelaryngeal glands; others run between the cricoid and first tracheal ring and enter the inferior deep cervical glands.
