Preferred Label : olecranon;
Uberon definition : The olecranon is a large, thick, curved bony eminence of the forearm that projects
behind the elbow. It is situated at the upper (proximal) end of the ulna, one of the
two bones in the forearm. When the hand faces forward the olecranon faces towards
the back (posteriorly). It is bent forward at the summit so as to present a prominent
lip which is received into the olecranon fossa of the humerus in extension of the
forearm. Its base is contracted where it joins the body and the narrowest part of
the upper end of the ulna. Its posterior surface, directed backward, is triangular,
smooth, subcutaneous, and covered by a bursa. Its superior surface is of quadrilateral
form, marked behind by a rough impression for the insertion of the Triceps brachii;
and in front, near the margin, by a slight transverse groove for the attachment of
part of the posterior ligament of the elbow-joint. Its anterior surface is smooth,
concave, and forms the upper part of the semilunar notch. Its borders present continuations
of the groove on the margin of the superior surface; they serve for the attachment
of ligaments, viz. , the back part of the ulnar collateral ligament medially, and
the posterior ligament laterally. From the medial border a part of the Flexor carpi
ulnaris arises; while to the lateral border the anconeus muscle is attached.;
