first cranial nerves

The nerves supplying the nasal olfactory mucosa. They consist of delicate bundles of unmyelinated fibers, the fila olfactoria, which pass through the cribriform plate and terminate in the olfactory bulb. The fila are the central processes of bipolar receptor neurons of the olfactory mucous membrane.
