The lacrimal, frontal, and nasociliary nerves.
The lacrimal nerve passes through the upper lateral aspect of the superior orbital fissure, outside the annulus of Zinn, and continues its lateral course in the orbit to terminate in the lacrimal gland, providing its sensory innervation.
Slightly medial to the lacrimal nerve within the superior orbital fissure is the frontal nerve, which is the largest of the first division of branches of the trigeminal nerve. It also crosses over the annulus of Zinn and follows a course over the levator to the medial aspect of the orbit, where it divides into the supraorbital and supratrochlear nerves. These provide sensation to the brow and forehead.
The nasociliary nerve is the sensory nerve of the eye. After entering through the medial portion of the annulus of Zinn, it lies between the superior rectus and the optic nerve. Branches to the ciliary ganglion and those forming the ciliary nerves provide sensory supply to the cornea, iris, and ciliary body. The terminal branches are the infratrochlear nerve, which supplies the medial portion of the conjunctiva and eyelids, and the anterior ethmoidal nerve, which provides sensation to the tip of the nose.
Cuneus and lingula. (The calcarine fissure extends forward from the occipital pole toward the splenium and divides this surface into an upper part, the cuneus, and a lower part, the lingula. The cuneus is a wedge-shaped lobule, bounded in front by the parieto-occipital sulcus, below by the calcarine sulcus, and above by the superior border of the hemisphere. The lingula, a narrow convolution between the calcarine sulcus and the lower border of the medial surface, has, as its name suggests, a tongue-like appearance with the tip of the tongue located at the occipital pole. The lingula blends anteriorly into the posterior part of the parahippocampal gyrus.)
