Lateral wall

The lateral wall (Paries lateralis) of the orbit is also caudal. In most domestic animals, it is absent on the dry skeleton, where the orbit communicates largely with the temporal fossa. On the living animal, it is made of the fibrous sheet that continues the one of the ventral wall and also connects on the orbital ligament or the caudal bony margin of the orbit (according to the species) and medially on the orbitotemporal crest (Crista orbitotemporalis) of the frontal bone. In Men, the ossification extends at the expense of this fibrous sheet and only leaves the narrow inferior fissure between the orbit and the temporal fossa.
