Which veins are classified as superficial veins of the upper extremity?

The basilic and cephalic veins are indeed classified as superficial veins of the upper extremity. Superficial veins are located closer to the surface of the skin and are more accessible for clinical procedures such as venipuncture.

The basilic vein runs along the inner side of the arm, while the cephalic vein is found on the outer side. Both of these veins drain blood from the superficial tissues of the upper arm and forearm and are often utilized in medical settings due to their size and accessibility.

In contrast, the other options include veins that are categorized as deep veins, such as the radial and ulnar veins, as well as the axillary and brachial veins, which lie deeper in the arm. The brachial and subclavian veins are also classified as deep veins, reflecting their location and function within the vascular system. Thus, the distinction as superficial veins accurately applies to the basilic and cephalic veins.
