Frontal vein
Encyclopedia
The frontal vein begins on the forehead
in a venous plexus which communicates with the frontal branches of the superficial 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 the 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
into the two angular veins.
Forehead
For the Arsenal striker see GervinhoIn human anatomy, the forehead is the fore part of the head. It is, formally, an area of the head bounded by three features, two of the skull and one of the scalp. The top of the forehead is marked by the hairline, the edge of the area where hair on the scalp...

Superficial temporal vein
-Path:It begins on the side and vertex of the skull in a plexus which communicates with the frontal vein and supraorbital vein, with the corresponding vein of the opposite side, and with the posterior auricular vein and occipital vein....

Orbit
In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the Solar System...

Supraorbital vein
The supraorbital vein begins on the forehead where it communicates with the frontal branch of the superficial temporal vein.It runs downward superficial to the Frontalis muscle, and joins the frontal vein at the medial angle of the orbit to form the angular vein.Previous to its junction with the...

Angular vein
The angular vein formed by the junction of the frontal vein and supraorbital vein, runs obliquely downward, on the side of the root of the nose, to the level of the lower margin of the orbit, where it becomes the anterior facial vein....

Human nose
The visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils...
