More or less extensive ossification is to be regarded as a normal occurrence, especially in the cartilages of the sternal ribs. The Sternum The sternum of the horse is shaped somewhat like a canoe; it is compressed laterally, except in its posterior part, which is flatteneil dorso-ventrally. It is inclined obliquely so that the posterior end is about six to eight inches (15 to 20 cm.) lower than the anterior. The dorsal surface (Facies dorsalis) has the form of a very narrow isosceles triangle with the apex in front. It is concave longi- tudinally, flattened transversely. The lateral surfaces (Facies laterales) are convex above, slightlj- concave below, and diminish in extent behind. Each presents on its upper part seven costal cavities (Foveae costales), with which the sternal ends of the second to the eighth costal cartilages inclu- sive articulate. These cavities are situated in series at the intersternebral junctions. The first four are elliptical in outline with the long diameter vertical, and are sepa- rated by considerable regular intervals. The others are progressively smaller, more circular, and closer together. The area attachment to the pectoral muscles. The dorso-lateral borders separate the dorsal and lateral surfaces. They give attachment to the lateral branches of the sternal ligament. The ventral border forms the prominent keel-like crest of the sternum (Crista sterni) which may be felt in the living animal; it fades out Ix' Xiphoid cnrtilage . —Sternum and Cos: Horse; Ventr-^l View.
