Apparatus located in the floor of the mouth, under the mandibular arcade. The apparatus consists of a central corpus and four pairs of processes. This apparatus serves as the site of insertion for a variety of muscles associated with movements of the tongue and as the origin of the m. hyoglossus.[AAO]

apparatus hyobranchialis
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).
