THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The olfactory nerve is a solely sensory nerve and conveys the sense of smell. Its receptors are located in the olfactory mucosa under the roof of the nasal cavity. The olfactory fibers cross the skull base through the olfactory foramina of the cribriform plate and enter the olfactory bulb in the olfactory groove.

Detailed explanation-2: -Your olfactory nerve is the first cranial nerve (CN I). It’s also part of your autonomic nervous system, which regulates body functions. This nerve enables your sense of smell.

Detailed explanation-3: -The olfactory nerve is the first cranial nerve and is instrumental in our sense of smell. The olfactory nerve contains only afferent sensory nerve fibers and, like all cranial nerves, is paired.

Detailed explanation-4: -Coffee and vanilla principally stimulate the olfactory cell receptors. Ammonia is a trigeminal nerve stimulator.
