MICROANATOMY

Detailed explanation-1: -Your olfactory nerve is the first cranial nerve (CN I). This nerve enables your olfactory system and sense of smell.

Detailed explanation-2: -The olfactory nerve is the first cranial nerve (CN I). It is a sensory nerve that functions for the sense of smell. Olfaction is phylogenetically referred to as the oldest of the senses. It is carried out through special visceral afferent nerve.

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: -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-5: -Olfaction, the sense of smell detects and discriminate odors as well as social cues which influence our innate re-sponses. The olfactory system in human beings is found to be weak as compared to other animals; however, it seems to be very precise.
