ORGANIZE! Anterior Forearm Muscle Innervation

The video tutorial explains the innervation of muscles in the forearm, focusing on the anterior compartment. It highlights the roles of the ulnar and median nerves, and their branches, in innervating different muscle layers. The tutorial also provides a strategy for remembering the innervation patterns, emphasizing the split innervation of the flexor digitorum profundus and the specific roles of the anterior interosseous nerve.

Which nerve is not involved in the innervation of the anterior forearm muscles?

• Median nerve

• Ulnar nerve

• Radial nerve

• Anterior interosseous nerve

Which muscle is part of the superficial layer of the anterior forearm?

• Flexor pollicis longus

• Pronator teres

• Flexor digitorum profundus

• Pronator quadratus

What is the only muscle in the intermediate layer of the anterior forearm?

• Flexor digitorum superficialis

• Flexor carpi ulnaris

• Flexor carpi radialis

• Palmaris longus

Which muscle is fully innervated by the ulnar nerve?

• Pronator teres

• Flexor carpi ulnaris

• Flexor digitorum superficialis

• Flexor carpi radialis

The flexor digitorum profundus has split innervation. Which nerve innervates its lateral half?

• Ulnar nerve

• Radial nerve

• Anterior interosseous nerve

• Median nerve

Which nerve innervates the flexor pollicis longus?

• Anterior interosseous nerve

• Radial nerve

• Median nerve

• Ulnar nerve

What is the strategy suggested for remembering the innervation of the anterior forearm muscles?

• Use a mnemonic for each muscle

• Understand the pattern of innervation

• Focus on the role of the radial nerve

• Memorize each muscle individually
