Muscles of forearm surrounded by...

antebrachial fascia, which is continuous with the brachial fascia

2

In general, the radial artery supplies the _________ of the __________ compartment, while the ulnar artery supplies most of the _________ compartment

radial; extensor; flexor

3

Generally, the functions of the forearm are:

- pronation/supination
- flex/extend wrist & digits
- assist in flexion of elbow
