Advanced Axillary Artery Quiz

Q1. Which relationship explains the names of the lateral, medial, and posterior cords of the brachial plexus?

• Their positions relative to the first rib
• Their positions relative to the clavicle
• Their positions relative to the second part of the axillary artery
• Their positions relative to the axillary vein

Q2. Which branch of the axillary artery provides a major connection between the axillary arterial system and the scapular anastomosis?

• Circumflex scapular artery
• Anterior circumflex humeral artery
• Superior thoracic artery
• Radial collateral artery

Q3. The circumflex scapular artery enters the posterior scapular region through which space?

• Quadrangular space
• Triangular space
• Cubital tunnel
• Triangular interval

Q4. Which pair of structures passes through the quadrangular space?

• Radial nerve and deep brachial artery
• Circumflex scapular artery and suprascapular nerve
• Ulnar nerve and superior ulnar collateral artery
• Axillary nerve and posterior circumflex humeral artery

Q5. Why can the scapular anastomosis help maintain upper limb perfusion if the axillary artery is gradually obstructed proximal to the subscapular artery?

• The axillary vein carries arterial blood around the obstruction
• The brachial artery normally bypasses the axillary artery
• Subclavian branches can communicate with the circumflex scapular branch of the subscapular artery
• The radial artery directly connects to the subclavian artery in the axilla

Q6. An injury involving the surgical neck of the humerus may damage which branch of the axillary artery?

• Superior thoracic artery
• Posterior circumflex humeral artery
• Deep brachial artery
• Thoracodorsal artery

Q7. An axillary artery aneurysm may produce neurological symptoms primarily because of the artery's close relationship with which structure?

• Brachial plexus
• Recurrent laryngeal nerve
• Vagus nerve
• Phrenic nerve

Q8. Which branch of the thoracoacromial trunk courses toward the deltopectoral groove and accompanies the cephalic vein?

• Clavicular branch
• Thoracodorsal branch
• Pectoral branch
• Deltoid branch

Q9. Which statement correctly distinguishes the termination of the axillary artery from its beginning?

• It begins at teres major and ends at the first rib
• It begins at the medial epicondyle and ends at the radial tuberosity
• It begins at the lateral border of the first rib and ends at the inferior border of teres major
• It begins at the clavicle and ends at the surgical neck of the humerus

Q10. Which description best summarizes the axillary artery?

• A forearm artery that divides into radial and ulnar branches
• A branch of the brachial artery confined to the posterior arm
• A continuation of the subclavian artery divided into three parts by pectoralis minor and continuing as the brachial artery
• A branch of the ulnar artery that supplies the scapular region
