Olecranon: The bony tip of the elbow. The olecranon is the near end of the ulna, the bone in the forearm, and it forms the pointed portion of the elbow. The triceps muscle tendon of the back of the arm attaches to the olecranon. Disease can affect the olecranon.

The styloid process of the ulna is found at distal end of the forearm, and projects from the medial and back part of the bone; it descends a little lower than the head, and its rounded end affords attachment to the ulnar collateral ligament of the wrist. The head is separated from the styloid process by a depression for the attachment
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. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus. Its upper
A fracture of the ulna alone (not involving the radius) usually occurs as a result of the ulna being hit by an object. The shaft is the most likely site of fracture. In this situation, the normal muscle tone will pull the proximal ulna posteriorly. Less commonly, the olecranon process

Olecranon bursitis may develop gradually, owing to repetitive irritation of the olecranon bursa, or acutely because of trauma or infection. The olecranon bursa lies in the posterior aspect of the elbow between the olecranon process of the ulna and the overlying skin.
Another notable prominence is the tuberosity of ulna. Elbow Joint: The head of the proximal ulna resembles a wrench, with a wide curved ‘c’ shaped surface formed by the trochlear or semilunar notch along with the olecranon process. The olecranon can be felt.
Proximal End of the Ulna The proximal end of the ulna articulates by trochlea of the humerus. To facilitate movement at the elbow joint.Landmarks of the proximal ulna are the coronoid process, olecranon, trochlear notch, radial notch and the ulnar tuberosity.
The olecranon process of the ulna fits into the olecranon groove and fossa in the humerus. The radial head also articulates with the capitellum of the humerus and with the proximal ulna to allow for pronation and supination of the forearm. Ulna ulna
21/10/2019 · The olecranon process acts as a site of attachment for several major muscles of the arm, including the triceps brachii and the flexor carpi ulnaris. It also prevents hyperextension of the elbow. Just below it on the anterior aspect of the ulna is the coronoid process, a smaller, pointy projection that serves as a site of attachment for the brachialis , pronator teres, and flexor digitorum muscles.
