Short head of biceps brachii |
O: tip of coracoid process of scapula I: tuberosity of radius and fascia of forearm via bicipital aponeurosis I: musculocutaneous C6 A: Supinates forearm, when Supinates flexes elbow joint, flexes shoulder, resist dislocation of shoulder |
|
|
Long head of biceps brachii |
O: supraglenoid tubercle of scapula I: tuberosity of radius and fascia of forearm via bicipital apoeurosis |
|
|
Brachialis |
O: distal half of anterior surface of humerus I: Coronoid process and tuberosity of ulna I: Musculocuteanous A: flexes elbow joint in all positions |
|
|
Coracobrachialis |
O: tip of coracoid process of scapula I: middle third of medial surface of humerus I: musculocutaneous nerve A: helps flex and addict shoulder joint, resists dislocation of shoulder |
|
|
Triceps long head |
O: infraglenoid tubercle of scapula I: proximal end of Olecranon of ulna and fascia of forearm I: radial nerve c7,8 A: chief extensor of the elbow joint, long head extends shoulder joint and resist dislocation of humerus ( especially important during abduction) |
|
|
Lateral head of triceps |
O: posterior surface of humerus , superior to radial groove I: proximal end of Olecranon of ulna and fascia of forearm I: radial nerve |
|
|
Medial head triceps brachii |
O: posterior surface of humerus, inferior to radial groove I: proximal end of Olecranon of ulna and fascia of forearm I; radial nerve |
|
|
Anconeus |
O: lateral epicondyle of humerus i: lateral surface of Olecranon and superior part of posterior surface of ulna I: radial nerve A: assists triceps in extending elbow joint, stabilizes elbow joint, abduct ulna during pronation |
