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.
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 ...
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 ...
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 ...
In comparative anatomy, the more neutral term entepicondyle is used. 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 humerus (/ ˈhjuːmərəs /; pl.: humeri) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes ...
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.
