Intermediate Common Interosseous Artery Quiz

Q1. The common interosseous artery usually arises from the ulnar artery shortly after which major arterial division?

• Bifurcation of the axillary artery
• Bifurcation of the brachial artery
• Formation of the deep palmar arch
• Division of the profunda brachii artery

Q2. Which branch usually arises from the posterior interosseous artery near its origin and ascends toward the elbow?

• Superficial palmar branch
• Inferior ulnar collateral artery
• Interosseous recurrent artery
• Radial recurrent artery

Q3. The interosseous recurrent artery contributes to which arterial network?

• Deep plantar arch
• Elbow anastomosis
• Scapular anastomosis
• Superficial palmar arch

Q4. Which artery commonly anastomoses with the interosseous recurrent artery posterior to the lateral epicondyle?

• Superior ulnar collateral artery
• Thoracoacromial artery
• Middle collateral artery
• Anterior circumflex humeral artery

Q5. Which nerve travels with the anterior interosseous artery in the deep anterior forearm?

• Superficial radial nerve
• Ulnar nerve
• Musculocutaneous nerve
• Anterior interosseous nerve

Q6. Which deep anterior forearm muscle receives blood through branches of the anterior interosseous artery?

• Flexor pollicis longus
• Extensor carpi radialis longus
• Brachioradialis
• Anconeus only

Q7. How does the posterior interosseous artery reach the posterior compartment of the forearm?

• It passes behind the medial epicondyle with the ulnar nerve
• It passes to the posterior forearm near the proximal interosseous membrane
• It passes through the carpal tunnel
• It passes through the quadrangular space

Q8. Which branch of the common interosseous artery contributes to the dorsal carpal arterial network distally?

• Profunda brachii artery
• Anterior interosseous artery
• Superior ulnar collateral artery
• Radial recurrent artery

Q9. Why is the common interosseous artery important despite its short length?

• It directly supplies the entire arm
• It is the only artery supplying the entire hand
• It is the principal artery of the axilla
• Its branches supply extensive deep regions of the forearm

Q10. Which sequence correctly describes the usual arterial pathway leading to the anterior interosseous artery?

• Ulnar artery, brachial artery, common interosseous artery, anterior interosseous artery
• Brachial artery, radial artery, profunda brachii artery, anterior interosseous artery
• Brachial artery, ulnar artery, common interosseous artery, anterior interosseous artery
• Axillary artery, radial artery, common interosseous artery, anterior interosseous artery
