olfactory nerve
Quick Summary
The olfactory nerve, also known as cranial nerve I, is responsible for the sense of smell. It originates from bipolar cells in the nasal mucosa. These cells' axons pass through the cribriform plate of the ethmoid bone into the cranial cavity, forming the olfactory nerve, which then terminates in the olfactory bulb.1
Damage to the olfactory nerve, often caused by head injuries or tumors, can lead to a reduced sense of smell or complete loss of smell (anosmia). This nerve is crucial for detecting odors and plays a role in flavor perception. The olfactory system, which includes the nose and nasal cavities, supports the olfactory mucous membrane where smell perception occurs.23

The physician tests the olfactory nerve by placing items with specific, mild odours, such as coffee, tar, or lemon, under the nose of the patient. The patient should be able to perceive, though not necessarily identify, the odour if the olfactory nerve is functioning correctly.
