The medial tarsometatarsal articulation comprises the internalcuneiform bone and the base of the first metatarsal bone (great toe).The ligaments are the capsule, and dorsal and plantar tarsometatarsalligaments. The intermediate tarsometatarsal joint comprises the threecuneiform bones and the bases of the second, third and a part of thefourth metatarsal bones. The ligaments are dorsal, plantar andinterosseous. The lateral tarsometatarsal articulation involves the cubo

One, a flat piece, liesbetween the common epiphysis of the astragalus and cal-caneum and the metatarsal bones of the foot, and is generallyconsidered to correspond to the cuboid of human anatomy.The other piece is a mere nodule on the inner or astragalarside, and is compared with the navicular bone of humananatomy. The foot has six toes. The first is minute
