Path
The nasociliary nerve enters the orbit between the two heads of the lateral rectus muscles and between the superior and inferior rami of the oculomotor nerve (CN III). It passes across the optic nerve (CN II) and runs obliquely beneath the superior rectus muscle and superior oblique muscle to the medial wall of the orbital cavity. It passes through the anterior ethmoidal opening as the anterior ethmoidal nerve and enters the cranial cavity just above the cribriform plate of the ethmoid bone. It supplies branches to the mucous membrane of the nasal cavity and finally emerges between the inferior border of the nasal bone and the side nasal cartilages as the external nasal branch.

Famous quotes containing the word path:
“The broken ridge of the hills
was the line of a lover’s shoulder,
his arm-turn, the path to the hills,
the sudden leap and swift thunder
of mountain boulders, his laugh.”
—Hilda Doolittle (1886–1961)
“The lesson which these observations convey is, be, and not seem. Let us acquiesce. Let us take our bloated nothingness out of the path of the divine circuits. Let us unlearn our wisdom of the world. Let us lie low in the lord’s power, and learn that truth alone makes rich and great.”
—Ralph Waldo Emerson (1803–1882)
“The path was a vague parting in the grass
That led us to a weathered windowsill.
We pressed our faces to the pane. “You see,” he said,
“Everything’s as she left it when she died....””
—Robert Frost (1874–1963)
