Examples from the Web for tarsometatarsus
The medial metatarsal depression is large; it is on the medial surface of the proximal end of the tarsometatarsus.
The lateral branch of the tendon on the tarsometatarsus is not ossified (true also of some legs of Tympanuchus).
About midway down the tarsometatarsus this tendon becomes ossified.
The insertion is tendinous on the posterior surface of the hypotarsus and along the posterolateral ridge of the tarsometatarsus.
The greater mass of the bipartite muscle probably makes possible a stronger extension of the tarsometatarsus.
- a bone in the lower part of a bird's leg consisting of the metatarsal bones and some of the tarsal bones fused together
C19: tarso-, from tarsus + metatarsus
