this notch is called the olecranon process; it articulates behind the humerus in the olecranon fossa and may be felt as the point of the elbow.
Where is the olecranon process located on the ulna?
The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm.
Where is the olecranon process located quizlet?
The olecranon process is located on the medial aspect of the ulna. In the anatomical position, the tuberosity of the radius is in close proximity to the lateral side of the ulna.
Which bone has olecranon process?
humerus. The two depressions—the olecranon fossa, behind and above the trochlea, and the coronoid fossa, in front and above—receive projections of the ulna as the elbow is alternately straightened and flexed.
Where is the olecranon fossa located?
The olecranon fossa is located on the posterior surface of the distal humerus, where it receives the proximal ulna during full extension of the arm.
What attaches to the olecranon process?
The olecranon (previously the olecranon process) of the ulna is the most proximal part of the bone. It is a massive, blunt process. The triceps brachii muscle, the primary extensor of the forearm, has its insertion on the tuberosity of this process.
What is dorsal olecranon?
The olecranon is part of the ulna bone of the forearm that makes the ‘point of the elbow’. The olecranon bursa is located over this bone to allow the skin to move easily over it.
What is the function of the olecranon process of the ulna?
Function. The olecranon fossa provides space for the olecranon of the ulna during extension of the forearm, from which it gets its name.
What does the olecranon of ulna articulate with?
The olecranon forms the upper part of the semi-lunar notch which is a smooth, large depression and articulates with the humeral trochlea during elbow flexion and extension.
Where is the greater tubercle of the humerus located?
The greater tuberosity it is located lateral to the head. The lesser tuberosity is located inferior to the head, on the anterior part of the humerus, Its very prominent and palpable. Bicipital (intertubercular) groove is located between the two tuberosities.
Where is the head of the radius located?
Near the elbow
The upper extremity of the radius (or proximal extremity) presents a head, neck, and tuberosity. The radial head has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum (or capitellum) of the humerus.
What does the medial epicondyle do?
The medial epicondyle gives attachment to the ulnar collateral ligament of elbow joint, to the pronator teres, and to a common tendon of origin (the common flexor tendon) of some of the flexor muscles of the forearm: the flexor carpi radialis, the flexor carpi ulnaris, the flexor digitorum superficialis, and the
What is the common name of the olecranon process?
A firm nodule can form at the tip of the elbow; it is referred to as an olecranon nodule and is sometimes found in gout or rheumatoid arthritis. Also known as the olecranon process of the ulna.
Is the olecranon process on the radius?
The radius has a large tuberosity on the front, toward the medial side. The proximal ulna has a large notch bounded by two bony processes. The olecranon process fits into the olecranon fossa of the humerus, while the coronoid process fits against the anterior surface of the humerus when the elbow is flexed.
Where is the trochlea located?
In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm.
