<P> The afferent nerve fibers of the olfactory receptor neurons , transmit nerve impulses about odors to the central nervous system , where they are perceived by the sense of smell ( 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 . </P>
