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. [citation ...
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.
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]
The ophthalmic artery (OA) is an artery of the head.It is the first branch of the internal carotid artery distal to the carotid 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.
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 ...

The supraorbital nerve is one of two terminal branches - the other being the supratrochlear nerve - of the frontal nerve (itself a branch of the ophthalmic nerve (CN V 1)). [1] It exits the orbit via the supraorbital foramen/notch before splitting into a medial branch and a lateral branch. It innervates the skin of the forehead, upper eyelid ...
The short posterior ciliary arteries contribute arterial supply to the choroid, ciliary processes, [3] optic disc, the outer retina, and Bruch's membrane. [1]Some branches of the short posterior ciliary arteries supply the optic disc by means of an anastomotic ring - the circle of Zinn-Haller or circle of Zinn - which is associated with the fibrous extension of the ocular tendons (common ...
