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 ...
There is a supraorbital foramen, an infraorbital foramen, a superior orbital fissure, an inferior orbital fissure and the optic canal, each of which contains structures that are crucial to normal eye functioning. The supraorbital foramen contains the supraorbital nerve, the first division of the trigeminal nerve or V1 and lies just lateral to ...
The superior orbital fissure is divided into 3 parts from lateral to medial: [citation needed] 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 sensory nerves of the forehead connect to the ophthalmic branch of the trigeminal nerve and to the cervical plexus, and lie within the subcutaneous fat. The motor nerves of the forehead connect to the facial nerve. [2] The ophthalmic branch of the trigeminal nerve, the supraorbital nerve, divides at the orbital rim into two parts in the ...
The supraorbital foramen, is a bony elongated opening located above the orbit (eye socket) and under the forehead. It is part of the frontal bone of the skull. The supraorbital foramen lies directly under the eyebrow. In some people this foramen is incomplete and is then known as the supraorbital notch. [1]
The central retinal artery is the first, and one of the smaller branches of the ophthalmic artery and runs in the dura mater inferior to the optic nerve. About 12.5mm (0.5 inch) posterior to the globe, the central retinal artery turns superiorly and penetrates the optic nerve , continuing along the center of the optic nerve, entering the eye to ...
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.
Supraorbital refers to the region immediately above the eye sockets, where in humans the eyebrows are located. It denotes several anatomical features, such as: It denotes several anatomical features, such as:
