What is the coronoid process of ulna?
The coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus.
What is the coronoid process in elbow?
The coronoid process acts as a bony buttress to prevent posterior dislocation and has three soft tissue insertions which lend stability as well: the anterior joint capsule of the elbow, the brachialis muscle and the medial ulnar collateral ligament.
What does the coronoid process of the ulna articulate with?
part of ulna …of the trochlear notch, the coronoid process, enters the coronoid fossa of the humerus when the elbow is flexed. On the outer side is the radial notch, which articulates with the head of the radius. The head of the bone is elsewhere roughened for muscle attachment.
What is the importance of coronoid process?
Also, it appears that the coronoid process may be particularly important as a stabilizing structure during elbow flexion between 60 and 105 degrees.
How many coronoid processes are there?
The coronoid process is a term given to two different structures found within the human body. The first is found on the jawbone, also referred to as the mandible. The other coronoid process is located on the ulna, a long bone found in the forearm.
What is coronoid process fracture?
Coronoid fractures are a break in the coronoid process of the ulna due to trauma or injury. A coronoid fracture of the ulna is a complex intraarticular fracture that is difficult to expose due to complex surrounding anatomical structures.
What contains the Coronoid process?
The coronoid process is found on the ulna and interfaces with the coronoid fossa of the humerus in the elbow.

Where does the Coronoid process take place?
What muscles attach to the Coronoid process?
The coracoid process serves as the attachment site for several muscles. The pectoralis minor is attached to the medial aspect of the coracoid. The coracobrachialis is attached to the tip of the process on the medial side, and the short head of the biceps is attached to the tip of the process on the lateral side.
Where does the Coronoid process insert?
Its medial surface gives insertion to the temporalis, and presents a ridge which begins near the apex of the process and runs downward and forward to the inner side of the last molar tooth….

What is a coronoid process fracture?
What is the coronoid process of the ulna?
coronoid process of the ulna. a bracketlike projection from the anterior portion of the proximal extremity of the ulna; its anterior surface gives attachment to the brachialis, and its proximal surface enters into the formation of the trochlear notch. coronoid process of the ulna. a wide, flaring projection of the proximal end of the ulna.
What is the function of the coronoid process in the elbow?
Frequently, the flexor pollicis longus muscle arises from the lower part of the coronoid process by a rounded bundle of muscular fibers. Function. The coronoid process stabilises the elbow joint and prevents hyperflexion. Clinical significance. The coronoid process can be fractured from its anteromedial facet. Additional images
What is the anterior process of the ulna?
Anatomical terms of bone. The Ulna’s coronoid process is a triangular eminence projecting forward from the anterior proximal portion of the ulna. Its base is continuous with the body of the bone, and of considerable strength.
