The thyrohyoid membrane is one of the extrinsic membranes that compose the larynx. It is a broad fibro-elastic layer named for its attachments as it attaches the upper border of the thyroid cartilage to the hyoid bone. The thicker median section of the membrane is the thyrohyoid ligament.

What penetrates the thyrohyoid membrane?

The internal branch of superior laryngeal nerve (IBSLN) pierces the thyrohyoid membrane above the entrance of superior laryngeal artery.
