Question: Where does the ophthalmic nerve exit the skull?

Disambiguated questions and answers:
context: The frontal branch passes through the orbit superiorly, then reenters the frontal bone briefly before exiting above the orbit through the superior orbital fissure and the supraorbital notch to provide sensory innervation for the skin of the forehead and scalp. The lacrimal nerve passes through the orbit superiorly to innervate the lacrimal gland. The nasociliary branch gives off several sensory branches to the orbit and then continues out through the anterior ethmoidal foramen, where it enters the nasal cavity and provides innervation for much of the anterior nasal mucosa. It also gives off a branch which exits through the nasal bones to form the external nasal nerve.

Long answers:
knowledge: content: The ophthalmic nerve (V1) is one of three divisions of the trigeminal nerve (CN V). 
wikipage: Ophthalmic nerve
long_answer: The ophthalmic nerve is one of three divisions of the trigeminal nerve. The frontal branch of the ophthalmic nerve exits the skull at the superior orbital fissure and supraorbital notch. The lacrimal nerve passes through the orbit superiorly when it exits the skull. The nasociliary branch goes through the nasal bones or through the anterior ethmoidal foramen. 

knowledge: content: The ophthalmic nerve (V1) is one of three divisions of the trigeminal nerve (CN V). It has three branches that provide sensory innervation to the eye, skin of the upper face and anterior scalp.

wikipage: Nasociliary nerve
long_answer: The ophthalmic nerve has three branches, the lacrimal nerve, the frontal nerve, and the nasociliary nerve. Its frontal branch exits the skull at the superior orbital fissure and supraorbital notch. Its lacrimal nerve passes through the orbit superiorly to exit the skull. Its nasociliary branch exits the skull through the anterior ethmoidal foramen.
