What is "cephalic vein"?

The cephalic vein is a prominent blood vessel located in the upper extremities of the human body. It runs along the outer side of the arm, originating from the hand and forearm, and ascends towards the shoulder region. The cephalic vein is responsible for draining blood from the superficial structures of the upper limb, including the hand, forearm, and lateral aspects of the arm. It plays a crucial role in venous circulation, carrying deoxygenated blood back to the heart. The cephalic vein is commonly used for venous access during medical procedures such as blood draws, intravenous therapy, and certain surgical interventions. Its visibility and accessibility make it a valuable vein for medical interventions and diagnostic purposes.
