Orbit

The hollow bony depression in the front of the skull in which each eye and lacrimal gland are situated.


Either of a pair of bony cavities in the skull that house the eyeball and associated structures; the eyeball socket.


Round circuit, pertaining to the eye or bony socket in the cranium that surrounds all but the anterior portion of the eye.


One of the two bony cavities in the skull that contains the eyes as well as its associated nerves, blood vessels, muscles, and other structures. Each orbit is made up of seven bones (maxilla, zygomatic, frontal, lacrimal, palatine, ethmoid, and sphenoid) and lies just above the sinus cavities of the nose.


The cavity in the skull that contains the eye. It is formed from parts of the frontal, sphenoid, zygomatic, lacrimal, ethmoid, palatine, and maxillary bones.


The bony pyramid-shaped cavity of the skull that contains and protects the eyeball. It is pierced posteriorly by the optic foramen (which transmits the optic nerve and ophthalmic artery), the superior and inferior orbital fissures, and several foramina. It is formed by the frontal, zygomatic, ethmoid, maxillary, lacrimal, sphenoid, and palatine bones.


The hollow space located within the skull that accommodates the eyeball is commonly referred to as the eye socket. This socket is formed by the fusion of seven distinct bones, namely the frontal, maxillary, sphenoid, lacrimal, zygomatic, ethmoid, and palatine bones. Together, these interconnected bones create a protective structure that cradles and supports the delicate anatomy of the eye within the confines of the skull.


The cranial socket housing the eyeball includes protective fat, blood vessels, muscles, and nerves. The optic nerve travels from the eye to the brain via an aperture at the rear of the orbital cavity.


A forceful impact to the face has the potential to result in an orbital fracture. However, the eyeball is typically unharmed as protective muscles instinctively push it backward during reflexive blinking. While many fractures can naturally mend without intervention, certain cases might lead to disfigurement, necessitating corrective surgery. In uncommon instances, bacterial infections can spread from the sinus or facial areas, giving rise to orbital cellulitis.
