Which of the following arteries is one of the first branches to form from the axis artery?

D. The median artery is one of the first branches to form from the axis artery. In the adult, the median artery does not persist and is probably reduced to a small unnamed vessel. This is why the median nerve does not have an accompanying artery in the adult like the ulnar nerve (ulnar artery) and radial nerve (radial artery).
