31. Olfactory receptors are activated by airborne chemical substances
dissolved in fluid on the
surface of nasal mucous membranes.
Olfactory nerves (CN i) are bipolar receptor cells found in the olfactory
epithelium on the epithelium on the roof of the nasal cavity. The nerves
travel through the ethmoid bone where the dendrites extend from the
cell body to the surface of the epithelium. Here it terminates in the
olfactory bulbs, which are paired masses of gray matter. IN the olfactory
bulbs, olfactory nerve axons synapse with other cell bodies of the
pathway. The axons travel together from the bulbs to the tracts which
carry the information to the temporal lobes. Here it is interpreted in the
primary olfaction are a s smell.

detectable by the brain.
