Is a small canal, which runs obliquely through the substance of the inferior paries of the orbit. It begins, behind, by a simple gutter, and divides, anteriorly, into two branches, one of which descends into the anterior paries of the maxillary sinus, whilst the other passes out, in the canine fossa, by an orifice, called Foramen-infra-orbitarium. The infra-orbitar artery and nerve pass along it.
