FMA. 38866. Anatomical terminology. [edit on Wikidata] MRI of the elbow (T1 weighted) showing an unimpaired radial collateral ligament and extensor tendon. The radial collateral ligament (RCL), lateral collateral ligament (LCL), or external lateral ligament[Explain 1] is a ligament in the elbow on the side of the radius.
TA2. 1773. FMA. 38854. Anatomical terminology. [edit on Wikidata] The humeroulnar joint (ulnohumeral or trochlear joint[1]) is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. [1] It is classified as a simple hinge-joint, which allows ...
Anatomical terms of bone. [edit on Wikidata] The lateral epicondyle of the humerus is a large, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint, and to a tendon common to the origin of the supinator and some of the extensor muscles. Specifically, these extensor muscles ...
Elbow. The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. [1] The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus.
During activities such as overhand baseball pitching, this ligament is subjected to extreme tension, which places the overhand-throwing athlete at risk for injury. [4] Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There ...
The radius is a long bone, prism -shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
Olecranon. The olecranon (/ oʊˈlɛkrənɒn /, from Greek olene 'elbow' and kranon 'head'), is a large, thick, curved bony process on the proximal, posterior end of the ulna. It forms the protruding part of the elbow and is opposite to the cubital fossa or elbow pit (trochlear notch). The olecranon serves as a lever for the extensor muscles ...
Radial tuberosity is visible at upper left of radius.) Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone. Ligaments that support the elbow joint also attach to the radial tuberosity.
