Inferior5
The infraorbital foramen is located 10 mm inferior to the zygomaxillary suture. (medscape.com)
The infraorbital sulcus crosses the floor of the orbit and carries the infraorbital artery, infraorbital vein, and infraorbital nerve from the inferior orbital fissure to the infraorbital foramen. (medscape.com)
It then runs anteriorly in the inferior aspect of the extraconal space within the infraorbital groove . (radiopaedia.org)
We now complete the latissionus dorsi, from the inferior thoracic branches of the foramina. (universalmetro.com)
The infraorbital foramen, for the nerve and artery of the same name, is less than 1 cm inferior to the inferior margin. (dartmouth.edu)
Artery2
It transmits the infraorbital artery and vein, and the infraorbital nerve, a branch of the maxillary nerve. (wikipedia.org)

Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side. (wikipedia.org)
After giving off numerous branches, the maxillary nerve eventually enters the face through the infraorbital canal, where it ends as the infraorbital nerve (see image below). (medscape.com)
The main trunk continues through the infraorbital canal within the floor of the orbit anteriorly, before emerging in the face through the infraorbital foramen lying between levator labii superioris and levator anguli oris muscles . (radiopaedia.org)

Branches1
At the point where it emerges on the face via the infraorbital foramen, the infraorbital nerve divides into three alveolar proximal branches and four distal branches. (pocketdentistry.com)
Arteries1
