The frontal vein (supratrochlear vein) begins on theforehead in a venous plexus which communicates with the frontal branches of thesuperficial temporal vein .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.
At the root of the nose the veins diverge, and, each at the medial angle of the
orbit , joins thesupraorbital vein , to form theangular vein .Occasionally the frontal veins join to form a single trunk, which bifurcates at the root of the
nose into the two angular veins.External links
