Quizplus · Accepted Answer

The olfactory nerve (cranial nerve I) is the only one that passes through the cribriform plate of the ethmoid bone, allowing for transmission of the sense of smell to the brain. The optic nerve (A) originates from the retina and passes through the optic canal, while the trigeminal nerve (C) is a mixed sensory and motor nerve that passes through the foramen ovale and foramen rotundum of the skull. The oculomotor nerve (D) and abducens nerve (E) both pass through the cavernous sinus, a venous structure in the skull.
