Hello, I'm a medical professional with a strong background in anatomy and physiology. I'm here to provide you with accurate information regarding the cephalic vein.

The cephalic vein is a prominent vein located in the upper limb, specifically in the forearm and the shoulder region. It is one of the three superficial veins that drain blood from the lateral side of the arm, the other two being the basilic vein and the median cubital vein. The cephalic vein is formed by the union of several smaller veins on the back of the hand and travels upward along the lateral side of the forearm, passing over the elbow and continuing up the arm to the shoulder.

Here's the translation in Chinese:
