Intermediate Superficial Palmar Arch Quiz

Q1. What is the relationship of the superficial palmar arch to the long flexor tendons of the fingers?

• It lies superficial to the long flexor tendons
• It lies within the flexor tendons
• It lies deep to the metacarpal bones
• It lies entirely on the dorsum of the hand

Q2. What is the relationship of the superficial palmar arch to the palmar aponeurosis?

• It lies within the extensor retinaculum
• It lies deep to the palmar aponeurosis
• It lies superficial to the skin
• It lies posterior to the metacarpals

Q3. Which palmar arch is generally located more distally in the hand?

• Neither arch lies in the hand
• Both always lie at exactly the same level
• Deep palmar arch
• Superficial palmar arch

Q4. Which vessels from the deep palmar arch commonly communicate with the common palmar digital arteries?

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

Q5. Where do common palmar digital arteries usually divide into proper palmar digital arteries?

• At the surgical neck of the humerus
• Near the interdigital web spaces
• At the elbow
• At the anatomical snuffbox

Q6. Which statement correctly compares the superficial and deep palmar arches?

• Both arches are formed exclusively by the ulnar artery
• The superficial arch lies behind the metacarpal bones
• The superficial arch is mainly radial and lies deeper and more proximally
• The superficial arch is mainly ulnar and lies more superficially and distally

Q7. Which arterial pathway most commonly supplies the adjacent sides of the middle and ring fingers?

• Axillary artery, circumflex humeral artery, proper palmar digital arteries
• Superficial palmar arch, common palmar digital artery, proper palmar digital arteries
• Brachial artery, anterior interosseous artery, proper palmar digital arteries
• Deep palmar arch, radial recurrent artery, proper palmar digital arteries

Q8. Why is the superficial palmar arch sometimes described as complete or incomplete?

• The arch disappears during finger extension
• The arch is present only in the dominant hand
• The presence and pattern of an anastomotic connection with another artery vary
• The arch normally becomes a vein in some individuals

Q9. Which artery is the most common source of the superficial palmar arch even when its completion pattern varies?

• Posterior interosseous artery
• Ulnar artery
• Deep brachial artery
• Brachial artery

Q10. Which sequence correctly traces the principal arterial pathway to the superficial palmar arch?

• Subclavian artery, ulnar artery, axillary artery, brachial artery, superficial palmar arch
• Subclavian artery, axillary artery, brachial artery, ulnar artery, superficial palmar arch
• Brachial artery, subclavian artery, radial artery, axillary artery, superficial palmar arch
• Axillary artery, radial artery, subclavian artery, ulnar artery, superficial palmar arch
