abductor pollicis longus,the extensor pollicis longus,and the extensor pollicis brevis

Anatomical snuff box contents are: Abductor Pollicis Longus, Extensor Pollicis Brevis, and Extensor Pollicis Longus. All of these are inervated by the radial nerve.

There are many muscles in the hand. Here are a few:

extensor carpi radialis brevis

extensor carpi radialis longus

extensor carpi ulnaris

extensor digitorum communis

extensor indicis proprius

extensor digiti minimi

abductor pollicis longus

extensor pollicis brevis

extensor pollicis longus

flexor carpi ulnaris

flexor digitorum profundus

flexor digitorum superficialis

flexor carpi radialis

flexor carpi ulnaris

palmaris longus

flexor pollicis longus

abductor pollicis brevis

opponens pollicis

adductor pollicis

palmaris brevis

abductor digiti minimi

flexor digiti minimi

Then each finger has a set of lumbrical muscles

and 3 volar and 4 dorsal muscles

Abductor Pollicis Brevis, Flexor Pollicis Brevis, Opponens Pollicis, Abductor Digiti Minimi, Flexor Digiti Minimi, Opponens Digiti Minimi, Adductor Pollicis, Lumbricals, Palmar Interossei, Dorsal Interossei, Abductor Pollicis Longus, Extensor Pollicis Brevis, Extensor Pollicis Longus, Extensor Indicis, Flexor Digitorum Superficialis, Flexor Digitorum Profundus, Palmaris Longus

The muscles that flex your fingers are located on the anterior side of the forearm and hand. The muscles that extend your fingers are located on the posterior side of the forearm and hand.

The abductor digiti minimi muscle abducts the fifth proximal phalanx. The abductor pollicis brevis abducts the thumb. The dorsal interossei muscles abduct the other fingers.
