Document Summary

The muscular system: appendicular musculature (based on chapter 11) Muscles of the pectoral girdle and upper limbs. **most of these muscles originate on the humerus and insert upon the forearm and wrist. Long head of triceps brachii: originates on the scapula and inserts on the olecranon of ulna (lateral and medial heads originate on humerus and insert on olacranon) Short and long head of biceps brachii: originate on the scapula and insert of the radial tuberosity of the radius. Biceps brachii: flexes at the elbow and shoulder (see above) Brachialis: flexes at the elbow (origin: humerus, insertion: forearm and wrist) Brachioradialis: flexes at the elbow (origin: humerus, insertion: forearm and wrist) Anconeus: extension at the elbow (origin: humerus, insertion: forearm and wrist) Triceps brachii: extension at elbow, extension and adduction at elbow (long head) (origin: scapula, insertion: ulna) Lateral head: extension at the elbow (origin: scapula, insertion: ulna)
