Which of the following vessels joins the Brachial Veins to form the Axillary vein?

The vessel that joins the Brachial Veins to form the Axillary vein is the Basilic vein. This vein is significant in the venous return pathway of the upper extremity. The Brachial veins, which typically consist of two paired veins accompanying the Brachial artery, merge with the Basilic vein at the level of the Axilla (armpit) to form the Axillary vein.

The Basilic vein is positioned medially along the arm and is responsible for draining blood from parts of the hand and forearm, contributing to venous return in the upper limb. Once it merges with the Brachial veins, it becomes the Axillary vein, which continues on to become the Subclavian vein.

In contrast, the other vessels — the Radial vein, Ulnar vein, and Cephalic vein — do not directly contribute to the formation of the Axillary vein. The Radial and Ulnar veins drain the forearm but do not merge with the Brachial veins; instead, they typically have their own pathways towards the larger venous systems. The Cephalic vein runs laterally and drains into the Axillary vein, but it does not combine with the Brachial veins to form
