GROSS ANATOMY

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

Detailed explanation-2: -The trigeminal nerve has receptors for pungent odorants throughout the nasal and pharyngeal cavities. The glossopharyngeal and vagus nerves provide the minor chemosensory function in the pharyngeal area. The ciliated olfactory receptors are part of the olfactory neuroepithelium.

Detailed explanation-3: -Parietal lobe It figures out the messages you receive from the five senses of sight, touch, smell, hearing and taste.

Detailed explanation-4: -The olfactory nerve, also known as the first cranial nerve, cranial nerve I, or simply CN I, is a cranial nerve that contains sensory nerve fibers relating to the sense of smell. The afferent nerve fibers of the olfactory receptor neurons transmit nerve impulses about odors to the central nervous system (olfaction).
