In veterinary anatomy, the term hyoid apparatus is the collective term used to refer to the bones of the tongue—a pair of stylohyoidea, a pair of thyrohyoidea, and unpaired basihyoideum [21] —and associated, upper-gular connective tissues. [22] In humans, the single hyoid bone is an equivalent of the hyoid apparatus. [23]

The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
The hyoid apparatus is the collective term used in veterinary anatomy for the bones which suspend the tongue and larynx. [1] It consists of pairs of stylohyoid, thyrohyoid, epihyoid and ceratohyoid bones, and a single basihyoid bone. [2] The hyoid apparatus resembles the shape of a trapeze, [3] or a bent letter "H". [4]
It attaches at the lesser horn of hyoid bone [1] [2] inferiorly, [citation needed] and (the apex of [1]) the styloid process of the temporal bone [1] [2] superiorly. [ citation needed ] The ligament gives attachment to the superior-most fibres of the middle pharyngeal constrictor muscle .
The mylohyoid muscle elevates the hyoid bone and the tongue. This is particularly important during swallowing and speaking. Alternatively, if other muscles are used to keep the position of the hyoid bone fixed, then the mylohyoid muscle depresses the mandible. [1] It also functions as reinforcing the floor of mouth. [1]
Its anterior surface is in relation with the thyrohyoid muscle, sternohyoid muscle, and omohyoid muscles, and with the body of the hyoid bone. It is pierced by the superior laryngeal nerve . [ 2 ] It is also pierced the superior thyroid artery , where there is a thickening of the membrane.
