The posterior surface is triangular, smooth, concave, and gives attachment to the arytenoid muscle and transversus.. The antero-lateral surface is somewhat convex and rough. On it, near the apex of the cartilage, is a rounded elevation (colliculus) from which a ridge (crista arcuata) curves at first backward and then downward and forward to the vocal process.
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]
Its main use is to draw the arytenoid cartilages forward toward the thyroid, thus relaxing and shortening the vocal folds. But, owing to the connection of the deeper portion with the vocal fold, this part, if acting separately, is supposed to modify its elasticity and tension, while the lateral portion rotates the arytenoid cartilage inward ...
The transverse arytenoid is an unpaired intrinsic muscle of the larynx. It is situated deep to the two oblique arytenoids ; the oblique and transverse arytenoids are often considered two parts of a single muscle - the interarytenoid (arytenoid) muscle (which is then said to have an oblique part and a transverse part).
During an arytenoidectomy, the surgeon removes the arytenoid cartilage. The arytenoid cartilages are a pair of pyramid-shaped structures in the larynx (voice box) that play an essential role in vocal sound production. Various techniques, such as laser surgery or conventional surgical instruments, may be employed based on the severity of the ...
Behind, they are bounded by the apices of the arytenoid cartilages, the corniculate cartilages, and the interarytenoid notch. [2] Within the posterior part of each aryepiglottic fold exists a cuneiform cartilage which forms a whitish prominence, the cuneiform tubercle. [citation needed] The aryepiglottic folds contain the aryepiglottic muscles.

The muscular process of arytenoid cartilage is the posterolateral projection of the (short, rounded, and prominent) lateral angle of the base of the arytenoid cartilage. The muscular process gives insertion to the posterior cricoarytenoid muscles behind, and to the lateral cricoarytenoid muscles in front.
