These are the main veins of upper limb with alot of clinical uses

The cephalic vein is a superficial vein of the upper limb and it's one of the two main veins of the arm. Its name derives from ‘cephalic’ meaning head, as the vein runs up to the shoulder. The superficial venous network is the source of blood for most blood tests, and is the easiest place to access venous blood. In this article we will discuss the anatomy and clinical relevance of the cephalic vein.
The cephalic vein drains the radial part of the hand, forearm and arm and communicates along its course with the basilic vein, which drains the ulnar part. The cephalic vein empties directly into the axillary vein.
Course
The cephalic vein drains the dorsal venous network of the hand that crosses the anatomical snuffbox, runs superficial to the radial styloid process and then ascends in the superficial fascia of the forearm. The cephalic vein then communicates with the basilic vein at the cubital fossa, via the median cubital vein. At this point the vein lies superficially in the lateral part of the elbow joint crease.
Drainage
It crosses the clavipectoral fascia and axillary artery to drain into the axillary vein below the clavicle. The axillary vein is renamed the subclavian vein once it passes the lateral border of the first rib, and the subclavian vein unites with the internal jugular vein to form the brachiocephalic vein.
BASILIC VEIN
The basilic vein, along with the cephalic vein, is one of the primary superficial veins that drain the upper limb 1. It courses through both the forearm and arm, and contributes to the formation of the axillary vein.
origin: ulnar aspect of the superficial venous network of the dorsum of the hand
location: courses upwards on the medial aspect of the forearm and arm
drainage: palm of the hand, medial aspect of the forearm and arm
tributaries: median cubital vein and median antebrachial vein
