Intermediate Digital Arteries Quiz

Q1. How many common palmar digital arteries typically arise from the superficial palmar arch?

• Five
• One
• Three
• Seven

Q2. Which vessels from the deep palmar arch commonly join the common palmar digital arteries?

• Palmar metacarpal arteries
• Circumflex humeral arteries
• Radial recurrent arteries
• Ulnar recurrent arteries

Q3. At approximately what level do common palmar digital arteries divide into proper palmar digital arteries?

• At the proximal forearm
• At the anatomical snuffbox
• Near the interdigital web spaces
• At the elbow

Q4. Which proper palmar digital artery commonly arises directly from the superficial palmar arch rather than from a common palmar digital artery?

• The artery to the lateral side of the forearm
• The artery to the ulnar side of the little finger
• The artery to the radial side of the thumb
• The artery to the radial side of the index finger

Q5. Which arterial system provides the main source of the common palmar digital arteries?

• Deep brachial arterial system
• Ulnar arterial system
• Posterior interosseous arterial system only
• Axillary circumflex arterial system

Q6. Which artery commonly gives rise to the princeps pollicis and radialis indicis arteries in the deep palm?

• Ulnar recurrent artery
• Posterior interosseous artery
• Radial artery
• Brachial artery

Q7. Which artery commonly divides into two branches that run along the sides of the thumb?

• Radial recurrent artery
• Princeps pollicis artery
• Posterior ulnar recurrent artery
• Anterior interosseous artery

Q8. Why do the digital arteries have important anastomotic connections?

• They provide collateral pathways for digital blood flow
• They connect directly to the axillary vein
• They replace the brachial artery during hand movement
• They prevent all blood from reaching the fingertips

Q9. Which tissues receive blood from branches of the proper palmar digital arteries?

• Multiple tissues of the digits, including skin and deeper structures
• Only the extensor muscles of the forearm
• Only the fingernails
• Only the carpal bones

Q10. Which sequence correctly traces a common arterial pathway to the adjacent sides of the fingers?

• Axillary artery, deep brachial artery, superficial palmar arch, proper palmar digital artery
• Ulnar artery, posterior interosseous artery, radial recurrent artery, proper palmar digital artery
• Radial artery, brachial artery, common palmar digital artery, proper palmar digital artery
• Ulnar artery, superficial palmar arch, common palmar digital artery, proper palmar digital artery
