|Nerve: Nasociliary nerve|
|Nerves of the orbit, and the ciliary ganglion. Side view.|
|Gray's||subject #200 888|
|To||long root of the ciliary ganglion, the long ciliary nerves, the infratrochlear nerve, and the ethmoidal nerves|
Here it passes through the anterior ethmoidal foramen, and, entering the cavity of the cranium, traverses a shallow groove on the lateral margin of the front part of the cribriform plate of the ethmoid bone, and runs down, through a slit at the side of the crista galli, into the nasal cavity.
Finally, it emerges, as the external nasal branch, between the lower border of the nasal bone and the lateral nasal cartilage, and, passing down beneath the Nasalis muscle, supplies the skin of the ala and apex of the nose.
