They are joined, immediately beneath the orbit, by filaments from the facial nerve, forming with them the infraorbital plexus. External links This ...
The inferior ophthalmic vein passes posterior-ward through the inferior orbit [4] upon the inferior rectus muscle.It passes across (not through) the inferior orbital fissure before either draining into the superior ophthalmic vein within the orbit, or passing through or below the common tendinous ring and exiting the orbit through the superior orbital fissure to empty into the cavernous sinus.
The infraorbital vein is a vein that drains structures of the floor of the orbit. It arises on the face and passes backwards through the orbit alongside infraorbital artery and nerve, exiting the orbit through the inferior orbital fissure to drain into the pterygoid venous plexus.
Sympathetic fibers supplying the eye separate from the carotid plexus within the cavernous sinus. They run forward through the superior orbital fissure and merge with the long ciliary nerves (branches of the nasociliary nerve) and the short ciliary nerves (from the ciliary ganglion). Sympathetic fibers in the short ciliary nerves pass through ...
orbital branches of pterygopalatine ganglion: maxilla-infraorbital foramen: 2: infraorbital artery infraorbital vein, tributary of pterygoid plexus: infraorbital nerve: sphenoid: middle cranial fossa: foramen ovale: 2: accessory meningeal artery, emissary vein connecting cavernous sinus with pterygoid plexus: mandibular nerve (V 3) lesser ...
The superior orbital fissure is a foramen or cleft of the skull between the lesser and greater wings of the sphenoid bone. It gives passage to multiple structures, including the oculomotor nerve , trochlear nerve , ophthalmic nerve , abducens nerve , ophthalmic veins , and sympathetic fibres from the cavernous plexus .
Internal carotid artery accompanied by the internal carotid plexus; These nerves, with the exception of CN V 2, pass through the cavernous sinus to enter the orbital apex through the superior orbital fissure. The maxillary nerve, division V 2 of the trigeminal nerve travels through the lower portion of the sinus and exits via the foramen ...
The superior ophthalmic vein is the only orbital vein whose course generally parallels the course of an orbital artery: it has a similar course as the ophthalmic artery [1] (however, the latter instead exits the orbit through the optic canal). [2] Within the orbit, the superior ophthalmic vein passes posterior-ward alongside the ophthalmic artery.
