In most mammals, including humans, the hyoid apparatus is shaped like a horseshoe. However, in humans, some of the bones of the hyoid apparatus are fused into a single bone called os hyoideum. In other animals such as frogs, the hyoid apparatus has a hyoid body that is chiefly comprised of hyaline cartilage and two pairs of processes (i.e. alary process and the posteriolateral process).
