Inferior Orbital Fissure
The inferior orbital fissure is formed by the sphenoid bone and the maxilla. It is located posteriorly along the boundary of the floor and lateral wall of the orbit. It transmits a number of structures, including: * the zygomatic branch of the maxillary nerve * the ascending branches from the pterygopalatine ganglion * the infraorbital vessels, which travel down the infraorbital groove into the infraorbital canal and exit through the infraorbital foramen * the inferior division of the ophthalmic vein Images File:Gray189.png, Left infratemporal fossa.
