The frontal vein (supratrochlear vein) begins on the
forehead in a venous plexus which communicates with the frontal branches of the
superficial temporal vein
The superficial temporal vein is a vein of the side of the head. It begins on the side and vertex of the skull in a network of veins which communicates with the frontal vein and supraorbital vein, with the corresponding vein of the opposite side, a ...
. 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

In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as ...

supraorbital vein, to form the
angular vein. Occasionally the frontal veins join to form a single trunk, which bifurcates at the root of the
nose
A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes ...
