The hyothyroid membrane (thyrohyoid membrane) is a broad, fibro-elastic layer, attached below to the upper border of the
thyroid cartilageand to the front of its superior cornu, and above to the upper margin of the posterior surface of the body and greater cornuaof the hyoid bone, thus passing behind the posterior surface of the body of the hyoid, and being separated from it by a mucous bursa, which facilitates the upward movement of the larynxduring deglutition.
Its middle thicker part is termed the middle hyothyroid ligament (ligamentum hyothyreoideum medium; middle thyrohyoid ligament), its lateral thinner portions are pierced by the superior laryngeal vessels and the internal branch of the
superior laryngeal nerve.
Its anterior surface is in relation with the
Thyreohyoideus, Sternohyoideus, and Omohyoideus, and with the body of the hyoid bone.
