The inferior tarsus (tarsus inferior; inferior tarsal plate) is smaller, is thin, is elliptical in form, and has a vertical diameter of about 5 mm (0.2 in). The free or ciliary margins of these plates are thick and straight.
There are three proximal tarsals, the tibiale, intermedium, and fibulare, named for their points of articulation with the bones of the lower limb. These are followed by a second row of four bones, referred to as the centralia (singular: centrale), and then a row of five distal tarsals, each articulating with a single metatarsal. In the great ...
Skeleton of foot. Lateral aspect. The lateral arch is composed of the calcaneus, the cuboid, and the fourth and fifth metatarsals. [1]Two notable features of this arch are its solidity and its slight elevation.
Navicular bone. Inferior view. Fracture of the navicular bone. The tibialis posterior is the only muscle that attaches to the navicular bone.
The tarsals of the midfoot, which are smaller and shorter than the hindfoot tarsals, appear well oriented to transmit loads between the hindfoot and forefoot; this is necessary for load transfer and locking of the foot complex into a rigid lever for late stance phase. Conversely, the midfoot bones and joints also allow for the transmission of ...
Its inferior surface has two facets, which are best seen in the fresh condition. [ 8 ] The medial , situated in front of the middle calcaneal facet, is convex, triangular, or semi-oval in shape, and rests on the plantar calcaneonavicular ligament ; the lateral , named the anterior calcaneal articular surface, is somewhat flattened, and ...

The dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
