Veins of the head and neck. (Frontal vein labeled at upper right.)
Head anatomy anterior view
|frontal branch of superficial temporal artery|
The veins converge to form a single trunk, which runs downward near the middle line of the forehead parallel with the vein of the opposite side.
The two veins are joined, at the root of the nose, by a transverse branch, called the nasal arch, which receives some small veins from the dorsum of the nose.
Occasionally the frontal veins join to form a single trunk, which bifurcates at the root of the nose into the two angular veins.
