Anatomical terminology |
Both the trachea and the thyroid are surrounded by a thin layer of fascia, which is separate from the thyroid capsule.[2] Posteriorly, this investing fascia fuses with the thyroid capsule, forming a thick suspensory ligament for the thyroid gland known as the ligament of Berry. The ligaments are attached chiefly to the cricoid cartilage, and may extend to the thyroid cartilage.
The thyroid gland and all thyroid swelling move with the swallowing/deglutition because the thyroid is attached to the cartilage of the larynx by the suspensory ligament of Berry.
Ligament of Berry also prevents the thyroid gland from sinking into the mediastinum.
