Inferior orbital fissure
From Wikipedia, the free encyclopedia
(Redirected from Inferior orbital)
The lateral wall and the floor of the orbit are separated posteriorly by the inferior orbital fissure which transmits the maxillary nerve and its zygomatic branch, the infraorbital vessels, and the ascending branches from the sphenopalatine ganglion.
It is formed by the sphenoid bone and maxilla.
