Preferred Label : tarsal bone;
Uberon definition : A bone that is part of the tarsal skeleton. Examples: calcaneus, talus, centralia.;
Uberon synonym : bone of ankle; bone of tarsus; ossa tarsi; bone of tarsal skeleton; ankle bone; ossa tarsalia;
Uberon related term : hind mesopodium; tarsal; bony tarsus; tarsus osseus;
Uberon Taxon note : In primitive tetrapods, such as Trematops, the tarsus consists of three rows of bones.
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 majority of tetrapods, including all of those alive today, this simple
pattern is modified by the loss and fusion of various of the bones.[3] In reptiles
and mammals, there are normally just two proximal tarsals, the calcaneus (equivalent
to the amphibian fibulare) and the talus (probably derived from a fusion of multiple
bones). In mammals, including humans, the talus forms a hinge joint with the tibia,
a feature especially well developed in the artiodactyls. The calcaneus is also modified,
forming a heel for the attachment of the Achilles tendon. Neither of these adaptations
is found in reptiles, which have a relatively simple structure to both bones.[3] The
fifth distal tarsal disappears relatively early in evolution, with the remainder becoming
the cuneiform and cuboid bones. Reptiles usually retain two centralia, while mammals
typically have only one (the navicular).[3] In birds, the tarsus has disappeared,
with the proximal tarsals having fused with the tibia, the centralia having disappeared,
and the distal bones having fused with the metatarsals to form a single tarsometatarsus
bone, effectively giving the leg a third segment;
