All of the following are structures in the lateral wall of cavernous sinus except:
(A) Occulomotor nerve (B) Ophthalmic nerve (C) Optic chiasma (D) Maxillary nerve
(C) Structures in the Lateral Wall of the Sinus, from above Downwards
(a) Oculomotor nerve: In the anterior part of the sinus. It divides into superior and inferior divisions which leave the sinus by passing through the superior orbital fissure:
(b) Trochlear nerve: In the anterior part of the sinus, it crosses superficial to the oculomotor nerve, and enters the orbit throught the superior orbital fissure;
(c) Ophthalmic nerve: In the anterior part of the sinus. It divides into the lacrimal, frontal and nasocillary nerves;
(d) Maxillary nerve: It leaves the sinus by passing through the foramen rotundum on its way to the pterygopalatine fossa.
(e) Trigeminal ganglion: The ganglion and its dural cave project into the posterior part of the lateral wall of the sinus.
