Brachium
| Question | Answer |
|---|---|
| Biceps brachii | Supinates forearm; strongly flexes supinated elbow; weak shoulder flexor; checks upward translation of humeral head during deltoid abduction |
| Brachialis | Strongly flexes forearm in all postions |
| Coracobrachialis | Helps to flex and adduct arm weakly |
| Triceps brachii | Extends the forearm powerfully; it is chief extensor of forearm; long head steadies head of abducted humerus |
| Anconeus | Assists triceps in extending forearm; stabilizes elbow joint; abducts ulna during pronation |
| Radial collateral (off Deep Brachial) | Radial current (off Radial) |
| Superior ulnar collateral(off Brachial) | Posterior ulnar recurrent(off Ulnar) |
| What nerve innervates biceps brachii, Coracobrachialis, Brachialis? | Musculocutaneous (C5,C6) |
| What nerve innervates Triceps brachii and Anconeus? | Radial (C5-T1) |
| Inferior ulnar collateral (off Brachial) | Anterior ulnar recurrent (off Ulnar) |
| Middle collateral (off Deep Brachial) | Posterior interosseous recurrent (off Common Interosseous) |
| Anterior Compartment | Biceps brachii and Brachialis |
| Posterior compartment | Triceps brachii and Anconeus |
| Medial brachial cutaneous and Medial antebrachial cutaneous | Medial Cord |
| Lateral superior cutaneous | Axillary |
| Lateral inferior cutaneous and Posterior cutaneous | Radial |
| Lateral antebrachial cutaneous | musculocutaneous |
