Wikipedia
first cranial nerve
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). Derived from the embryonic nasal placode, the olfactory nerve is somewhat unusual among cranial nerves because it is capable of some regeneration if damaged. The olfactory nerve is sensory in nature and originates on the olfactory mucosa in the upper part of the nasal cavity. From the olfactory mucosa, the nerve (actually many small nerve fascicles) travels up through the cribriform plate of the ethmoid bone to reach the surface of the brain. Here the fascicles enter the olfactory bulb and synapse there; from the bulbs (one on each side) the olfactory information is transmitted into the brain via the olfactory tract. The fascicles of the olfactory nerve are not visible on a cadaver brain because they are severed upon removal. : 548

first cranial nerve
The first cranial nerve, also known as the olfactory nerve, is the first pair of twelve cranial nerves that are responsible for the sense of smell. This nerve transmits sensory data to the brain, specifically to the olfactory cortex, relating to smells detected by cells in the nasal cavity. It consists of numerous small unmyelinated fibers that pass through the openings in the cribriform plate of the ethmoid bone, and it is unique as it is the only cranial nerve that can regenerate.
