[1] It is the muscle principally responsible for extension of the elbow joint (straightening of the arm). FOIA The patient presents after a painful popping sensation with pain and swelling over the posterior elbow with the inability to extend the elbow against resistance. The examiner then, without the knowledge of the patient taps the triceps tendon with a reflex hammer. Action: As the medial head does not attach to the scapula and therefore has no action on the glenohumeral joint, whether with stabilization or movement.

Insertion: Proximal end of olecranon process of ulna and fascia of forearm. It represents the only constituent of the posterior muscle group of the arm, spanning almost the entire length of the humerus. In case of chronic rupture, the surgery is often followed by remodeling techniques before completing with rehabilitation period. Since the long head of the biceps originates from the infaglenoid tubercule, it plays a role in stabilizing the head of the humerus while the arm is outstretched sideways. Serratus Anterior Identify the highlighted muscle. Static contraction movements include pullovers, straight-arm pull-downs, and bent-over lateral raises, which are also used to build the deltoids and latissimus dorsi.

Anconeus- To palpate the anconeus, the landmark would be lateral condyle of the humerus to the proximal ulna & instruct the patient to extend the elbow. It can be worked out in isolation or with compound elbow extension movements. the 'struthers arcade' is a thin ligamentous- structure or a thickening of the brachial fascia or muscle fibers- of the medial head of the triceps muscle which extend to the- medial intermuscular septum or a combination of above. It consists of a long head, a medial head, and a lateral head. Routine cadaver dissection has resulted in the identification of a fourth head of the triceps brachii muscle on the left side in one specimen.

Identify the head of the triceps brachii muscle. In addition, its long head contributes to the extension and adduction of the arm at the shoulder joint. Additional supply to the lateral head of the triceps brachii is provided by the posterior circumflex humeral artery. The lateral head originates from an oblique ridge above the spiral groove on the upper part of the posterior surface of the shaft of the humerus. The long head of the triceps brachii (LHT) originates from the infraglenoid tubercle of the scapula via a short strong tendon (Romanes, 1964 ).
