1) Forearm
2) 5 muscles

- extensor carpi radialis brevis
- extensor digitorum
- extensor digiti minimi
- extensor carpi ulnaris
3) Forearm
Step-by-step explanation:

Extensor carpi radialis brevis
- this is to extend and abduct the wrist.
- this is It is shorter and thicker
- this can be be found above the proximal end
Extensor digitorum
-this extends the medial four digits of the hand
Extensor digiti minimi
- this it moves the back of the hand toward the back of the forearm
Extensor carpi ulnaris
-this is located on the ulnar side of the forearm
