Infraorbital nerve

from Wikipedia, the free encyclopedia
Trigeminal nerve of man

The infraorbital nerve (“sub-ocular nerve ”) is the direct continuation of the maxillary nerve ( cranial nerve V 2 ) after the other branches branch off. It pulls from the wing and palate fossa ( pterygopalatine fossa ) below the eye socket through the maxillary foramen ( maxillary foramen ) into the lower eye canal ( infraorbital canal ) of the upper jaw .

In the lower eye canal, the infraorbital nerve sends rami alveolares to all teeth of the upper jaw and supplies them sensitively. The terminal branch of the nerve emerges from the upper jaw at the lower eye opening ( foramen infraorbitale ). Here it can be palpated ( 2nd trigeminal pressure point ) or anesthetized . After emerging from the hole, it branches into the skin of the entire front and upper face and supplies them sensitively.
