Name of bone

Talus (Latin: Astragalus

Location/Articulation

The talus is the second largest of the tarsal bones. It occupies the middle and upper part of the tarsus, supporting the tibia above, resting on the calcaneus below, articulating on either side with the malleoli and in front with the navicular. It consists of a body (articulating with the tibia and fibula), a head (articulating with the navicular) and a neck, connecting the body and the head.
