The video describes the muscles of the posterior (extensor) compartment of the forearm:
Correction at 20:40: the 2 extensors of the thumb are: EPL and EPB
It is mentioned clearly at 21:40
A. Superficial group: 7 muscles, from lateral to medial:
1. Brachioradialis
2. Extensor carpi radialis longus.
3. Extensor carpi radialis brevis.
4. Extensor digitorum.
5. Extensor digiti minimi.
6. Extensor carpi ulnaris.
7. Anconeus
B. Deep group: 5 muscles, from above downward:
1. Supinator.
2. Abductor pollicis longus.
3. Extensor pollicis brevis.
4. Extensor pollicis longus.
5. Extensor indicis.
All the muscles are supplied by the posterior interosseous nerve (deep branch of the radial nerve) EXCEPT brachioradialis, extensor carpi radialis longus and anconeus which are supplied by the radial nerve itself.
NOTE:
@ 2 Extensors of the thumb: extensor pollicis longus and extensor pollicis brevis
@ 2 Extensors of the index finger: extensor digitorum and extensor indicis.
@ 2 Extensors of the little finger: extensor digitorum and extensor digiti minmi
