What does the thyrohyoid membrane do?
The thyrohyoid membrane connects the thyroid cartilage to the hyoid bone and facilitates the superior movement of the larynx during swallowing. It is separated from the hyoid body by a bursa that facilitates this upward movement during swallowing.
What pierces through the thyrohyoid membrane?
The thinner, lateral (side) portions of the thyrohyoid membrane are pierced by the internal laryngeal artery and the internal laryngeal nerve, which is a branch of the superior laryngeal nerve. This nerve helps sense the presence of mucus in the larynx, or voice box, and is part of the coughing reflex.
What does the superior laryngeal artery do?
The superior laryngeal artery accompanies the internal laryngeal branch of the superior laryngeal nerve, beneath the thyrohyoid muscle. It pierces the thyrohyoid membrane, and supplies the muscles, mucous membrane, and glands of the larynx, anastomosing with the branch from the opposite side.
What is a thyrohyoid?
The thyrohyoid muscle is an infrahyoid muscle of the neck that is innervated by the ventral ramus of C1. The primary function of the thyrohyoid muscle is to depress and fix the hyoid bone and larynx though it may also raise the larynx when the hyoid bone is fixed.
What is thyrohyoid membrane made of?
It is comprised of a cartilaginous skeleton, muscles, mucosal lining, ligaments, and membranes. 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.
How can you tell if you have superior thyroid?
Location. The superior thyroid artery branches off of the external carotid artery just below the chin. From there, it runs upward inside of a structure called the carotid triangle. Then it turns downward and runs beneath the muscles along the front of the neck.
What nerve runs with superior laryngeal artery?
internal laryngeal nerve
The superior laryngeal artery branches from the superior thyroid artery. This artery pierces the thyrohyoid membrane with the internal laryngeal nerve and helps supply the larynx.
What artery supplies the thyrohyoid?
superior laryngeal artery
The superior laryngeal artery accompanies the internal laryngeal branch of the superior laryngeal nerve, beneath the thyrohyoid muscle.
What is the thyrohyoid membrane?
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.
How does thyroid cancer affect the thyrohyoid membrane?
Thyrohyoid membrane. If a neck cancer affects the thyroid cartilage or the thyrohyoid membrane, it may result in a spreading of the tumor from the laryngeal area into the soft neck tissues. If a cancer deeply invades the area known as the paraglottic space after passing through the thyrohyoid membrane, it will not face any more barriers…
What is the middle hypothyroid membrane called?
The middle, thicker part of the thyrohyoid membrane is called the middle hypothyroid ligament. The membrane’s anterior (front) surface is near the omohyoid, thyrohyoid, and sternohyoid muscles.
What is thyrohyoid syndrome?
Thyrohyoid syndrome is also known as hyoidynia, hyoid bursitis, or lateral thyrohyoid ligament syndrome. 1 A patient with this condition typically (but not always) has a history of placing stress on this connective tissue in his or her profession or activities—trumpet playing, for example.
