Deltopectoral interval contains which vessel?

Deltopectoral interval contains which vessel?

• A. Cephalic vein
• B. Basilic vein
• C. Axillary artery
• D. Radial nerve

Answer: (A)

The deltopectoral interval is the space between the deltoid and pectoralis major in the upper arm, a key pathway for superficial structures. Within this interval runs the cephalic vein, a prominent superficial vein that travels up the lateral aspect of the arm and empties into the axillary vein after piercing the clavipectoral fascia. This location makes the cephalic vein the vessel contained in the deltopectoral interval. The other vessels don’t reside in this interval: the basilic vein lies medially, the axillary artery is deeper and more medial behind the pectoralis minor, and the radial nerve courses in the posterior arm around the humerus rather than in this superficial groove.
