. The anatomy of the domestic animals. Veterinary anatomy. Articular surface Extensor process Depression for collateral ligament ?face ')orsal Aiiun ' K^!'il border ffroove Fig. si.—Third Ph.\ of Horse: Later KV View. a, 6, Anterior and posterior extremities of cartilage- Laterally the height diminishes, and the slope becomes steeper, especiaUj^ on the nietlial side. From side to side the curvature is almost semicircular. The surface is rough and porous, resembling pumice stone somewhat. It is perforated by nu- merous foramina of various sizes; a series of larger ones is situated on or near the distal border. On either side the dorsal groove (Sulcus dorsalis)- passes forward from the angle ami ends at one of the larger foramina. In the fresh state this surface is covered by the corium of the wall of the hoof. The distal border is thin, sharp, and irregularly notched; there is commonly a ?ft'ider notch in front. The volar surface (Facies volaris) is arched, and divided into two unecjual parts liy a curved rough line, the semi- lunar crest (Crista semilunaris). The larger area in front of the crest is cres- cent-shaped, concave, and compara- tively smooth; it corresponds to the sole of the hoof, anfl may be termed the sole surface. The part behind the crest is much smaller, and is semilunar; it is related to the deep flexor tendon, and is hence called the flexor surface (Facies flexoria). It presents a central prominent rough area, on either side of which is the volar foramen (Foramen volare), to which the volar groove (Sulcus volaris) conducts from the angle.' The foramina lead into the semilimar canal (Canalis semilunaris) within the bone, from which small canals lead to some of the foramina of the dorsal sur- ' Formerly termed the pjTamidal process. - Formerly termed the preplantar groove.
