olecranon

Insertion of this large muscular mass is effected by means of several tendons to the olecranon.

The ulna or postaxial bone is somewhat expanded distally, but is not drawn out proximally into an olecranon process.

Its proximal end is large and convex, but is not drawn out into an olecranon process.

The ulna of Notoryctes has an enormous hooked olecranon which causes the bone to be nearly twice as long as the radius.

In the Carnivora vera the humerus has large tuberosities, a prominent deltoid ridge and a deep olecranon fossa.
