The hyoid is aneminently elastic bone,consisting of equal por-tions of organic andearthy matter. The cor-nua are largely cartilagi-nous in character. This bone develops by five centres,one for the body and one for each cornu. THE THORAX. The thorax is formed by the sternum and costalcartilages in front, the bodies of the vertebrae behind,laterally by the ribs. It is an osseo-cartilaginous struc-ture, flattened antero-posteriorly, is highly elastic, andsusceptible of an increase in all its diameters by theaction of the muscles of respiration. It contains theheart, lungs, great vessels and nerves. THE STERNUM. The sternum, or breast-bone, is a flat bone situatedin the median line, articulating with the clavicle above. ^x Onu-hjuridlQgoMk!^ 8(eni«-kymt; Fig. 44.—The Hyoid Bone. 98 PRACTICAL ANATOMY. and at the sides with the costal cartilages.
