Muscles and Arteries of the Forearm

The video tutorial covers the anatomy and function of the superficial and deep flexor muscles of the anterior forearm. It introduces a mnemonic to remember the superficial muscles and details each muscle's origin, insertion, action, and blood supply. The tutorial also discusses the unique aspects of the brachioradialis muscle, which is innervated by the radial nerve, unlike the other muscles in the anterior forearm.

What is the mnemonic used to remember the five most superficial muscles of the anterior forearm?

• FDS on PF

• PF on FDS

• PFPF on FDS

• FDS on PFPF

Which muscle is responsible for pronation of the forearm by bringing the radius towards the ulna?

• Flexor carpi ulnaris

• Pronator teres

• Flexor carpi radialis

Which muscle's action includes flexion and abduction of the wrist?

• Pronator teres

• Flexor carpi ulnaris
