. The comparative anatomy of the domesticated animals. Veterinary anatomy. 78 THE HEAD OF THE CAT. Parieto-occipital suture; 2, parietal bone; 3, frontal bone; 4, orbital piocess of the frontal bone; 5, malar bone; 6, supermaxil- lary bone ; 7, 7, premaxilla ; 8, nasal bone; 9, tympanic bulb ; 10, inferior maxilla. in its curved portion; the interdental space is very long; and the body has only two alveoli for the incisors. 11.—The Hyoid Bone (Fig. 47). The hi/oid bone constitutes a small and special bony apparatus which serves to support the tongue, as well as the Fig- -iS. larynx and pharynx ; its description is placed immediately after that of the bones of the head because of its con- nection with that region, it being situ- ated between the two branches of the supermaxillarybone, and suspended from the base of the cranium in an oblique direction from above to below, and from before to behind. This apparatus is composed of seven distinct pieces, arranged in three series : a middle, constituted by a single bone, and named the body; two lateral, form- ing two quasi-parallel branches, to the extremities of which the body is articu- lated. Body or basihijal.—The body of the hyoid resembles a fork with two prongs. It presents : 1. A middle part flattened above and below, and consequently provided with a superior and an inferior face. 2. A single and long pro- p's- '*^' longation flattened on both sides, which is de- tached from the middle part, and directed forward and downward to plunge into the muscular tissue of the tongue : this is the anterior appendix of the hijoideaJ body, or Ungual prolongation. 3. Two late- ral cornua, thyroid cornua, great cornua, or urohyals, projecting backwards and upwards, articulating by their extremities with the thyroid cartilage of the larynx, and offering, at their point of union with the middle part, two con- vex diarthrodial facets looking upwards, and corresponding with the styloid cormia.
