Study Notes
Biceps and Triceps Muscles
- The long head of the biceps muscle originates from the scapula, specifically the supraglenoid tubercle.
- The biceps muscle is supplied by the musculocutaneous nerve.
- The insertion of the biceps muscle is into the radial tuberosity.
- The biceps muscle is a powerful supinator and flexor of the elbow.
Triceps Muscle
- The lateral head of the triceps muscle originates from the posterior surface of the humerus, above the radial groove.
- The long head of the triceps muscle originates from the infraglenoid tubercle of the scapula.
- The insertion of the triceps muscle occurs at the olecranon process of the ulna.
Coracobrachialis Muscle
- The coracobrachialis muscle originates from the coracoid process of the scapula.
- The coracobrachialis muscle is supplied by the musculocutaneous nerve.
- The action associated with the coracobrachialis muscle is flexion of the arm at the shoulder joint.
