The coronoid process of the ulna is a triangular process projecting forward from the anterior proximal portion of the ulna. Structure
The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow.It takes the form of a small, flattened band, extending distally and laterally, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity. [1]
Between these two bands a few intermediate fibers descend from the medial epicondyle to blend with a transverse band which bridges across the notch between the olecranon and the coronoid process. This ligament is in relation with the triceps brachii and flexor carpi ulnaris and the ulnar nerve , and gives origin to part of the flexor digitorum ...
The deep head is much smaller, and more muscular in texture. It arises from the posterior third of the lower border and from the whole of the medial surface of the zygomatic arch. Its fibers pass downward and forward, to be inserted into the upper half of the ramus as high as the coronoid process of the mandible. The deep head of the muscle is ...
The anterior oblique ligament (AOL) attaches from the undersurface of the medial epicondyle to the medial ulnar surface slightly below the coronoid process. [12] It is the sturdiest of the three sections within the UCL. The AOL acts as the primary restraint against valgus stress at the elbow during flexion and extension.
The Coronoid process (from Greek korone, "like a crown") can refer to: . The coronoid process of the mandible, part of the ramus mandibulae of the mandible; The coronoid process of the ulna, a triangular eminence projecting forward from the upper and front part of the ulna
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 tuberosity of the ulna is a rough eminence on the proximal end of the ulna.It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body.
