The larynx is a short, quadrangular cavity, larger above than below, com-posed chiefly of a series of cartilages connectedby muscles and ligaments, and lined by mucousmembrane. Its position is in front of the verte-bral column, from which it is separated by thepharynx; in front, it is directly beneath the in-teguments; above, it opens into the pharynx, andbelow into the trachea. The cartilaginous basis of the larynx consistsof five principal parts called the thyroid, the cri-coid, the two arytenoid and the epiglottis carti-lages, together with some subordinate structuresof the same kind.
