| Abductor policis longus abductor policis brevis extensor policis longus extensor policis brevis | Name muscles that extend or abduct the thumb |
| False (it supplies also brachioradialis m. which is a weak flexor of forearm) | Radial nerve supplies only extensors of forearm |
| False (brachioradialis m. lies in posterior compartment and it is a flexor) | All flexors of forearm lie in anterior compartment |
| True | Flexors are 2x times stronger than extensors |
| All flexors and pronators of forearm are supplied by ulnar n. and median n. | Name supply of pronators and flexors of forearm |
| Radial n. | Name supply of extensors and supinators of forearm |
| Ulna radius interosseous membrane | What separates flexors from extensors? |
| Palmar carpal lig. flexor retinaculum | What is holding flexors in place |
| Flexor carpi radialis m. flexor carpi ulnaris m. palmaris longus m. pronator teres m. | What flexors are in the superficial group of forearm muscles |
| Flexor digitorum superficialis | What flexors are in the intermediate group of forearm muscles |
| Flexor digitorum profundus flexor pollicis longus pronator quadratus | What flexors are in the deep group of forearm muscles |
| Flexor carpi ulnaris medial part of flexor digitorum profundus | Name flexors of forearm innervated by ulnar n. |
| Lateral part of flexor digitorum profundus flexor pollicis longus pronator quadratus | Name all muscles innervated by anterior interosseous n. (from median n.) |
| Pronator teres flexor carpi radialis palmaris longus flexor digitorum superficialis | Name muscles of forearm innervated directly by median n. |
| Radial n. | All extensors/supinators of forearm are innervated by... |
| 1. muscles that abduct/adduct the hand at wrist joint 2. muscles that extend the medial four fingers 3. muscles that extend or abduct the thumb | What physiological groups can we divide extensors of forearm in? |
| Extensor carpi radialis longus extensor carpi radialis brevis extensor carpi ulnaris | Name muscles that abduct/adduct the hand at wrist joint |

| (act on thumb and index) abductor pollicis longus extensor pollicis brevis extensor pollicis longus extensor indicis | What muscles are in the depp layer of extensors ? |
| Brachioradialis extensor carpi radialis longus | What extensors are innervated directly by radial n.? |
| Extensor carpi radialis brevis extensor digitorum extensor digiti minimi extensor carpi ulnaris supinator | What extensors are innervated by deep branch of radial n.? |
| Extensor indicis abductor pollicis longus extensor pollicis longus extensor pollicis brevis | What muscles are innervated by posterior interosseous n. (from deep branch of radial n.) |
