Lesions
Lesions to the olfactory nerve can occur because of blunt trauma, such as coup-contra-coup damage, meningitis, and tumors of the frontal lobe. They often lead to a reduced ability to taste and smell. However, lesions of the olfactory nerve do not lead to a reduced ability to sense pain from the nasal epithelium. This is because pain from the nasal epithelium is not carried to the central nervous system by the olfactory nerve; rather, it is carried to the central nervous system by the trigeminal nerve (cranial nerve V).

Famous quotes containing the word lesions:
“Not that success, for him, is sure, infallible.
But never has he been afraid to reach.
His lesions are legion.
But reaching is his rule.”
—Gwendolyn Brooks (b. 1917)
