Which foramen is located between the frontal and ethmoidal bones and transmits the anterior ethmoidal nerve?

Which canal transmits the optic nerve and the ophthalmic artery?

Through which structure do the trochlear, oculomotor, and abducent nerves pass?

Which foramen transmits the zygomatic branches?

Which structure is located posteriorly between the maxilla and the greater wing of the sphenoid?

The Right Orbit

Inferior Orbital Fissure is located posteriorly between the maxilla and the greater wing of the sphenoid, communicating with the pterygopalatine fossa, and transmits maxillary nerve, zygomatic branch, inferior ophthalmic vein, and sympathetic nerves.
Superior Orbital Fissure is located posteriorly between the greater and lesser wings of the sphenoid, communicating with the middle cranial fossa, and transmits lacrimal, frontal, and nasociliary branches of the ophthalmic division of the trigeminal nerve, trochlear, oculomotor, and abducent nerves, as well as the superior ophthalmic vein.

Nerve and Vessel Passages

Optic Canal, located in the body of the sphenoid, communicates with the middle cranial fossa, and transmits the optic nerve and the ophthalmic artery.

Ethmoidal Foramina

Anterior Ethmoidal Foramen, located between the frontal and ethmoidal bone, transmits the anterior ethmoidal nerve and vessels.
Posterior Ethmoidal Foramen, located between the frontal and ethmoidal bone, transmits the posterior ethmoidal nerve and vessels.

Zygomatic Foramen

Zygomatic Foramen (1 or 2 openings) is located in the zygomatic bone and transmits the zygomatic branches.
