Orbit

Orbit

The orbit is four-sided and pyramidal in structure, housing the globe, optic nerve, the four rectus and two oblique muscles, the lacrimal gland, orbital fat, the cranial nerves III–VI, the ophthalmic artery with its tributaries and the ophthalmic veins, which anastomose anteriorly with the face and posteriorly with the cranial cavity . Above is the frontal lobe of the brain, temporally the temporal fossa, inferiorly the maxillary sinus and nasally the lacrimal sac and ethmoidal and sphenoidal air sinuses. The optic nerve passes through the optic canal to the chiasm, with other nerves and vessels passing through the superior ophthalmic fissure. Orbit
