foot arches

foot arches

hemidomed foot structure has longitudinal and transverse arches, i.e. forming upper half of a longitudinally curved cone (apex at heel; distal limit formed by metatarsal heads) with curvature maintained by bony architecture, directional pull of tendons of extrinsic musculature, and plantar and intermetatarsal ligaments; the longitudinal arch is more marked medially (i.e. medial longitudinal arch, formed by calcaneum, talus, navicular and first, second and third metatarsals) and very shallow laterally (i.e. lateral arch, formed by calcaneum, cuboid, fourth and fifth metatarsals); transverse arch is steep at midfoot (formed by tarsal bones, i.e. medial, intermediate and lateral cuneiforms, cuboid and associated metatarsal bases) and shallow at metatarsal heads (medial height of which is maintained by paired flexor hallucis brevis sesamoids underlying first metatarsal head
