Its tributaries include the basilic vein and cephalic vein, which are both superficial veins. It terminates at the lateral margin of the first rib, at which it becomes the subclavian vein.

Most of its course is superficial; it generally travels in the subcutaneous fat and other fasciae that lie superficial to the muscles of the upper extremity. Because of this, it is usually visible through the skin. Near the region anterior to the cubital fossa, in the bend of the elbow joint, the basilic vein usually connects with the other large superficial vein of the upper extremity, the cephalic vein, via the median cubital vein. The layout of superficial veins in the forearm is highly variable from person to person, and there are generally a variety of other unnamed superficial veins that the basilic vein communicates with. About halfway up the arm proper (the part between the shoulder and elbow), the basilic vein goes deep, travelling under the muscles. There, around the lower border of the teres major muscle, the anterior and posterior circumflex humeral veins feed into it, just before it joins the brachial veins to form the axillary vein. Along with other superficial veins in the forearm, the basilic vein is a possible site for venipuncture." xsd:string {source="WP,unvetted"}

 property_value: taxon_notes "In humans, Usually fully regressed before birth, its purpose is to supply nutrient to the developing lens in the growing fetus. During the tenth week of development the lens grows independent of a blood supply and the hyaloid artery usually regresses. Its proximal portion remains as the central artery of the retina. Regression of the hyaloid artery leaves a clear central zone through the vitreous called the hyaloid canal or Cloquet's canal. Occasionally the artery may not fully regress, resulting in the condition persistent hyaloid artery. More commonly, small remnants of the artery may remain. Free remnants can sometimes be seen as 'floaters'. An anterior remnant of the hyaloid artery can be seen in some people as Mittendorf's dot, a small pinpoint-like scar on the posterior surface of the lens. A posterior remnant may be seen where the artery left the optic disc, and is known as Bergmeister's papilla" xsd:string
