Infraorbital foramen

In human anatomy, the infraorbital foramen is an opening in the maxillary bone of the skull located below the infraorbital margin of the orbit. It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve. It is typically 6.10 to 10.9 mm (0.240 to 0.429 in) from the infraorbital margin.[1]

Structure

Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side.

The ramifications of the three principal branches of the trigeminal nerve—at the supraorbital, infraorbital, and mental foramen—are distributed on a vertical line (in anterior view) passing through the middle of the pupil. The infraorbital foramen is used as a pressure point to test the sensitivity of the infraorbital nerve.[2] Palpation of the infraorbital foramen during an extraoral examination or an administration of a local anesthetic agent will cause soreness to the area.[3]

gollark: Hold on while I check the config, though.
gollark: You should probably not be hardcoding sizes.
gollark: Not just "it's like WINDOWS, but for ComputerCraft, and actually not really like Windows as much as just a start menu, desktop and one GUI program".
gollark: They're typically significantly more interesting and creative.
gollark: Copy-pasting this from two months ago:Wild theory on new people constantly wanting to make an OS: they think something like "Oh wow, CC is so unlike Windows! And I have never seen any desktop OS but Windows! I must make it more like Windows so it is more familiar. Clearly nobody else has done this, or it would already be the default, because this is obviously better." Not explicitly/exactly that obviously, but think this might be close to what's going on.
