Fig 08-29 Horse metacarpus and metatarsus, left sides. Dorsal view of a metacarpus (A), dorsal view of a metatarsus (B), plantar view of a metatarsus (C), and volar view of a metacarpus (D). The horse has a single main metacarpus (third metacarpal) and metatarsus (third metatarsal). The remnants of the second and fourth metacarpals and second and fourth metatarsals can be seen in the volar/plantar views (shown on the right). These “splint bones” (lateral metapodia) taper to a point more than half way down the shaft of the main metapodial.
