The supraorbital artery is a branch of the ophthalmic artery. It passes anteriorly within the orbit to exit the orbit through the supraorbital foramen or notch alongside the supraorbital nerve , splitting into two terminal branches which go on to form anastomoses with arteries of the head.
The ophthalmic artery (OA) is an artery of the head. It is the first branch of the internal carotid artery distal to the cavernous sinus . Branches of the ophthalmic artery supply all the structures in the orbit around the eye , as well as some structures in the nose , face , and meninges .
recurrent meningeal branch of lacrimal artery (anastomotic branch of lacrimal artery with the middle meningeal artery) [citation needed] The superior orbital fissure is divided into 3 parts from lateral to medial: [citation needed]

The supraorbital foramen is a small groove at superior and medial margin of the orbit in the frontal bone. It is part of the frontal bone of the skull. [2] It arches transversely below the superciliary arches and is the upper part of the brow ridge. It is thin and prominent in its lateral two-thirds, but rounded in its medial third. [3]
The frontal branch of the superficial temporal artery (anterior temporal) runs tortuously upward and forward to the forehead, supplying the muscles, skin, and pericranium in this region, and anastomosing with the supraorbital and frontal arteries. In an estimate of the path of the nerve in the soft tissue of the temporal frontal branch using ...
The supratrochlear nerve is the smaller of the two terminal branches of the frontal nerve (the other being the supraorbital nerve). [1] It arises midway between the base and apex of the orbit [2] where the frontal nerve splits into said terminal branches.
After branching from the ophthalmic artery, it passes anteriorly through the superomedial orbit. It travels medial to the trochlear nerve. With the supratrochlear nerve, the supratrochlear artery exits the orbit through the supratrochlear notch (variably present), medial to the supraorbital foramen. It then ascends on the forehead.
