Uberon definition : The semilunar notch of the ulna (trochlear notch of ulna, greater sigmoid cavity)
is a large depression, formed by the olecranon and the coronoid process, and serving
for articulation with the trochlea of the humerus. About the middle of either side
of this notch is an indentation, which contracts it somewhat, and indicates the junction
of the olecranon and the coronoid process. The notch is concave from above downward,
and divided into a medial and a lateral portion by a smooth ridge running from the
summit of the olecranon to the tip of the coronoid process. The medial portion is
the larger, and is slightly concave transversely; the lateral is convex above, slightly
concave below.;
