The basilic vein is one of the three main veins of the upper limb, the others being the cephalic vein and the deep brachial vein. It originates in the venous network of the back of the hand. Then, it winds around towards the border of the anterior side (belly) of forearm. Running up along the forearm and the inner side of arm, the basilic vein drains deoxygenated blood into the axillary vein. This large blood vessel is superficial and can be seen in lean muscular persons.
