DEFINITION 7
The superior orbital fissure is a foramen in the skull, although
strictly it is more of a cleft, lying between the lesser and
greater wings of the sphenoid bone.
TERM 8
Inferior Orbital Fissure
DEFINITION 8
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, and the ascending
