The supratrochlear artery (or frontal artery) is one of the terminal branches of the ophthalmic artery. It arises within the orbit. [1] [2] It exits the orbit alongside the supratrochlear nerve. It contributes arterial supply to the skin, muscles and pericranium of the forehead. [3]
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 supratrochlear artery to the midline forehead. The supratrochlear artery is a branch of the ophthalmic branch of the internal carotid artery. the supraorbital artery to the lateral forehead and scalp as far up as the vertex. The supraorbital artery is a branch of the ophthalmic branch of the internal carotid artery. external carotid
The angular artery is an artery of the face. It is the terminal part of the facial artery. It ascends to the medial angle of the eye's orbit. It is accompanied by the angular vein. It ends by anastomosing with the dorsal nasal branch of the ophthalmic artery. It supplies the lacrimal sac, the orbicularis oculi muscle, and the outer side of the ...
It exits the orbit through the supratrochlear notch or foramen. [3] It then ascends onto the forehead beneath the corrugator supercilii muscle and frontalis muscle. It finally divides into sensory branches. [citation needed] The supratrochlear nerve travels with the supratrochlear artery, a branch of the ophthalmic artery. [2]
Lateral part transmits: superior ophthalmic vein, lacrimal nerve, frontal nerve, trochlear nerve (CN IV), recurrent meningeal branch of lacrimal artery (anastomotic branch of lacrimal artery with the middle meningeal artery)

The veins anastomose frequently with each other and enter the diploic veins of the skull bones and the dural sinuses. This is an extra difficulty as the vein pattern differs. The scalp veins accompany the arteries and have similar names: Anterior: Supratrochlear vein and supraorbital vein; Lateral: Superficial temporal vein; Posterior ...
