Paired processes that extend posterolaterally from the posterior margin of the hyoid plate. These processes are the ossified posteromedial processes and invest the laryngeal apparatus.[AAO]

The hyoid bone is derived from the lower half of the second gill arch in fish, which separates the first gill slit from the spiracle. In many animals, it also incorporates elements of other gill arches, and has a correspondingly greater number of cornua. Amphibians and reptiles may have many cornua, while mammals (including humans) have two pairs, and birds only one. In birds, and some reptiles, the body of the hyoid is greatly extended forward, creating a solid bony support for the tongue. The howler monkey Alouatta has a pneumatized hyoid bone, one of the few cases of postcranial pneumatization of bones outside Saurischia.
