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 .
These muscles have a common tendinous attachment at the medial epicondyle of the humerus at the elbow joint. [ 1 ] The flexor and pronator muscles of the forearm include the pronator teres , flexor carpi radialis , palmaris longus , and flexor digitorum superficialis , all of which originate on the medial epicondyle and are innervated by the ...
Tennis elbow or lateral epicondylitis is a chronic or an acute inflammation of the tendons that arise from the outer part of the elbow. The affected tendons are the tendons of extensor muscles which originate from the lateral epicondyle of humerus. It is caused by the repetitive movements and overuse.
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 ...
Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: . a posterior, rough portion, for the insertion of the tendon of the biceps brachii.
The bone or other structure the muscle is attached to that remains immobile during the action. The term "bone" is omitted from bone names. Insertion The attachment point of the muscle, on a bone or otherwise, that moves during the action. Artery The artery which supplies the muscle with blood. The term "artery" is included to avoid confusing ...
The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. [1] When the hand faces forward ( supination ) the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the ...
The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow. It lies beneath the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit). It originates from the anterior aspect of the distal humerus; [1] it inserts onto the tuberosity of the ulna.
