Summary of Muscles

Anterior Forearm

Pronator TeresOrigin Humeral head from medial

epicondyle and supracondylar ridge of humerus.Ulnar head from medial border of coronoid process of ulna

Insertion Middle of lateral surface of radius

Action Pronates and flexes forearm (at elbow)

Nerve Supply Median nerve (C6 and C7)Blood Supply Ulnar artery, anterior

recurrent ulnar artery

Posterior Forearm

BrachioradialisOrigin Proximal 2/3 of lateral

supracondylar ridge of humerus

Insertion Lateral surface of distal end of radius (base of styloid process)

Action Flexes forearmNerve Supply Radial nerve (C5, C6 and C7)

Blood Supply Radial recurrent artery

Anterior ArmBiceps Brachii

Origin Short head: tip of coracoid process of scapula; Long head: supraglenoid tubercle of scapula

Insertion Tuberosity of radius and fascia of forearm via bicipital aponeurosis

Action Supinates and flexes forearmNerve Supply Musculocutaneous nerve (C5

and C6) Blood Supply Muscular branches of brachial

artery
