Kashinatha Shenoy M, Gopalakrishna K, and Preetha

The orbits are boney cavities lodging the eyeballs, extraoccular muscles, nerves, blood vessels and lacrimal gland. Out of 12 pairs of cranial nerves; 2nd, 3rd, 4th, 6th,a part of 5th and some sympathetic fibers are are also present in the orbit. Nature has provided orbit for the safety of the eyeball. The long axis of the each orbit passes backwards and medially. The medial walls are parallel to each other at a distance of 2.5 cms but the lateral walls are set at right angles to each other.
