The tarsal bones—calcaneus, talus, navicular, cuboid, and three cuneiforms (medial, intermediate, lateral)—form the proximal skeletal framework of the foot, each with a defined spatial arrangement and articular relationships that connect the leg (via the talus's trochlear surface articulating with the tibia and fibula) through to the metatarsals and phalanges. This structural organization follows a proximal-to-distal pattern analogous to the hand, with the metatarsals and phalanges (two phalanges for digit one, three for digits two through five) forming the distal segments, and specific bony landmarks (e.g., the calcaneal sustentaculum tali, calcaneal tuberosity, cuboid groove) serving as attachment sites or passages for tendons, vessels, and nerves. This is a topic in human anatomy, specifically osteology of the foot/lower limb.
