Intermediate Deep Brachial Artery Quiz

Q1. At approximately what level does the deep brachial artery usually arise from the brachial artery?

• Within the palm
• At the wrist
• Near the proximal part of the brachial artery
• At the distal radioulnar joint

Q2. Which structures bound the triangular interval through which the deep brachial artery passes?

• Clavicle, first rib, and pectoralis minor
• Teres minor, surgical neck of humerus, and deltoid
• Biceps brachii, brachialis, and pronator teres
• Teres major, long head of triceps, and humerus or lateral head of triceps

Q3. What is the relationship between the deep brachial artery and radial nerve in the radial groove?

• They travel together along the posterior humerus
• They remain in separate compartments throughout the arm
• The artery travels with the median nerve instead
• The radial nerve ends before reaching the artery

Q4. Which branch of the deep brachial artery accompanies the radial nerve toward the lateral side of the distal arm?

• Superior ulnar collateral artery
• Radial collateral artery
• Interosseous recurrent artery
• Middle collateral artery

Q5. The radial collateral artery commonly anastomoses with which artery near the lateral epicondyle?

• Anterior interosseous artery
• Radial recurrent artery
• Superior ulnar collateral artery
• Ulnar artery

Q6. The middle collateral artery commonly anastomoses with which artery near the posterior elbow?

• Radial recurrent artery
• Interosseous recurrent artery
• Anterior ulnar recurrent artery
• Superior ulnar collateral artery

Q7. Which head of the triceps brachii lies deep to much of the course of the deep brachial artery and radial nerve in the radial groove?

• No head of triceps
• Short head
• Medial head
• Long head only

Q8. Which branch of the deep brachial artery descends posterior to the lateral epicondyle?

• Anterior ulnar recurrent artery
• Superior ulnar collateral artery
• Middle collateral artery
• Radial collateral artery

Q9. Why is the deep brachial artery important to the collateral circulation around the elbow?

• It supplies only the shoulder and does not reach the elbow region
• It directly forms the superficial palmar arch
• It becomes the ulnar artery at the elbow
• Its collateral branches anastomose with recurrent arteries around the elbow

Q10. Which sequence correctly describes the usual arterial pathway to the radial collateral artery?

• Axillary artery, radial artery, deep brachial artery, radial collateral artery
• Subclavian artery, ulnar artery, deep brachial artery, radial collateral artery
• Axillary artery, brachial artery, deep brachial artery, radial collateral artery
• Brachial artery, ulnar artery, common interosseous artery, radial collateral artery
