The intertarsal joints are between the tarsal bones.There are four groups of foot joints: intertarsal, tarsometatarsal, metatarsophalangeal, and interphalangeal. Medial plantar muscles: abductor hallucis, adductor hallucis, flexor hallucis brevisīesides the ankle joint which connects the foot with the leg, the bones of the foot articulate among themselves through many synovial joints. Lateral plantar muscles: abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimiĬentral plantar muscles: flexor digitorum brevis, quadratus plantae, lumbricals, plantar interossei, dorsal interossei Movements: foot inversion, foot eversion, toe flexion, toe extension, toe abduction, toe adductionĭorsal muscles: extensor digitorum brevis, extensor hallucis brevis Interphalangeal: great toe has one interphalangeal joint, other four toes have a two (proximal, distal) interphalangeal joints Metatarsophalangeal: connect the metatarsals with the proximal phalanges Tarsometatarsal: articulations between the tarsals and metatarsals Intertarsal: subtalar (talocalcaneal), talocalcaneonavicular, calcaneocuboid, cuneonavicular, cuboideonavicular, intercuneiform joints Phalanges: great toe consists of two phalanges (proximal, distal), the remaining four toes have three phalanges (proximal, middle, distal) Metatarsals: connect the tarsals and phalanges Mnemonic for tarsals: Tiger Cubs Need MILC Tarsals: proximal (talus, calcaneus), intermediate (navicular), distal (cuboid, cuneiforms) bones Lower ankle joint: talus, calcaneus, navicular bonesĪnkle ligaments: medial collateral ligament, deltoid ligament, lateral collateral ligament Upper ankle joint: inferior surfaces of tibia and fibula, superior surface of talus Key facts about the ankle and foot Ankle anatomy Thus, this page is dedicated to the anatomy of the ankle and foot. This is why the anatomy of the foot might roughly resemble the anatomy of the hand but is still different enough to have different functions. ![]() Then we could underline our anatomy textbook with our hands, and make flashcards with our feet at the same time.īut, evolution has refined our feet to be compatible with walking bipedally. If you’ve watched a documentary film about primates likes chimps or orangutans you may have thought how useful it would be if we could use our feet the same way we use our hands. ![]()
