Other causes of damage to these nerves include head traumaand tearing of the nerves, smoking, cocaine, or brain tumors impinging on the nerves. Optic Nerve (CN-II): Sensory for vision. Its nerve arise from the ganglion cells of the retina and pass through theoptic foramen (optic canal).agus Nerve (CN-X): Mixed: sensory and motor. Passes through the jugular foramen. It passes through the neck nextto the carotid arteries, after which the two travel together next to the esophagus through thediaphragm into the abdomen.
Optic Nerve. The 2nd cranial nerve. The optic nerve conveys visual information from the retina to the brain. The nerve carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain.ptic Nerve. The 2nd cranial nerve.
