It is separated from the hyoid bone by a mucous bursa, which allows for the upward movement of the larynx during swallowing. [1] Its middle thicker part is termed the median thyrohyoid ligament. [1] Its lateral thinner portions are pierced by the superior laryngeal vessels and the internal branch of the superior laryngeal nerve. [1]
It is the inlet to another cavity in the lateral wall of larynx, the laryngeal ventricle. The vestibular fold is formed by the vestibular ligament extending from the lateral walls of the epiglottis to the arytenoid cartilage covered with mucous membrane. The vocal fold is the upper free margin of the conus elasticus which is covered by mucous ...
In the human larynx, the cuneiform cartilages (from Latin: cuneus 'wedge' + forma 'form'; also known as cartilages of Wrisberg) are two small, elongated pieces of yellow elastic cartilage, placed one on either side, in the aryepiglottic fold. [1] The cuneiforms are paired cartilages that sit on top of and move with the arytenoids. [2]
The lateral cricoarytenoid (also anterior cricoarytenoid) is an intrinsic muscle of the larynx. It attaches at the cricoid cartilage anteriorly, and at the arytenoid cartilage of the same side posteriorly. It is innervated by the recurrent laryngeal nerve. It acts to close the rima glottidis, thus closing the airway.
The cricothyroid muscle is the only tensor muscle of the larynx aiding with phonation. It is innervated by the superior laryngeal nerve. It is innervated by the superior laryngeal nerve. Its action tilts the thyroid forward to help tense the vocal cords , thus increasing the pitch of the voice.
The lateral thyrohyoid ligament (lateral hyothyroid ligament) is a round elastic cord, which forms the posterior border of the thyrohyoid membrane and passes between the tip of the superior cornu of the thyroid cartilage and the extremity of the greater cornu of the hyoid bone.
The aryepiglottic folds are triangular folds of mucous membrane of the larynx.They enclose ligamentous and muscular fibres. They extend from the lateral borders of the epiglottis to the arytenoid cartilages, hence the name 'aryepiglottic'.
