Their main function is to prevent sweat, water, and other debris from falling down into the eye socket, but they are also important to human communication and...

The supraorbital foramen arches transversely below the superciliary arches

Superciliary arches

On the squama frontalis of the frontal bone of the skull, below the frontal eminences, and separated from them by a shallow groove, are two arched elevations, the superciliary arches; these are prominent medially, and are joined to one another by a smooth elevation named the glabella.Typically, the...

 and is the upper part of the margin of the orbit, thin and prominent in its lateral two-thirds, rounded in its medial third, and presenting, at the junction of these two portions, the supraorbital notch or foramen for the supraorbital nerve

Supraorbital nerve

The supraorbital nerve is a terminal branch of the frontal nerve.It passes through the supraorbital foramen, and gives off, in this situation, palpebral filaments to the upper eyelid...

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...
