1.3.2 Cartilage skeleton of the larynx
Cartilaginous skeleton of the larynx (Illustration 1) consists of three impaired cartilages (cricoid, thyroid, and epiglottic) and of three paired cartilages (pyramidal apex, cuneate vocal processes, arytenoid). All of these, combined by ligaments and muscles, define a cylindrical shape of the organ, characteristic to all airways.
Larynx is framed with a hyoid bone on its top, which resembles a horseshoe. Free vertical movement of the larynx depends on the position of the tongue and the lower jaw. Being attached but movable, the larynx is suspended from its one side to the lower jaw, and from the other to the muscles of the upper chest and shoulder blade.
