Laryngeal cartilages are cartilages which surround and protect the larynx. They form during embryonic development from pharyngeal arches. There are a total of nine laryngeal skeleton in humans: Thyroid cartilage - unpaired; Cricoid cartilage - unpaired; Epiglottis - unpaired; Arytenoid cartilages - paired; Corniculate cartilages - paired
There are nine cartilages, three unpaired and three paired (3 pairs=6), that support the mammalian larynx and form its skeleton. [4] Unpaired cartilages: Thyroid cartilage: This forms the Adam's apple (also called the laryngeal prominence). It is usually larger in males than in females.
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).
The arytenoid muscle / ær ɪ ˈ t iː n ɔɪ d / or interarytenoid muscle is a composite intrinsic muscle of the larynx, consisting of a transverse part and an oblique part - the two parts may be considered as separate muscles: an unpaired transverse arytenoid muscle, and a bilaterally paired oblique arytenoid muscle.
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]
The function of the cricoid cartilage is to provide attachments for the cricothyroid muscle, posterior cricoarytenoid muscle and lateral cricoarytenoid muscle muscles, cartilages, and ligaments involved in opening and closing the airway and in speech production. [citation needed]
