| | Considering that only 5% of the human nasal mucosa is olfactory epithelium as opposed to 50% in rats (Keyhani et al., 1997; Kimbell et al., 1997), one can question the importance of olfactory nerve translocation for UFP in humans. | | | This not generally recognized clearance pathway from the nasal mucosa to the CNS could be of significance for induction of neurotoxic effects following acute or chronic exposures to environmental or occupational UFP. | | | C in the olfactory bulb of rats which led us to hypothesize that routes for extrapulmonary translocation of solid UPF other than via the blood circulation exist, i.e., involving neuronal pathways from deposits on the nasal olfactory mucosa via the olfactory nerve. |

| | However, smell is the most important and neurally the most elusive because it is more directly involved with emotion and memory than the other senses. | | | Usually, recovery occurs unless there is significant, prolonged exposure with chronic damage to the olfactory mucosa. For example, many long term smokers, state that they have a loss in the sense of smell. | | | The most common cause of a loss in the sense of smell is a temporary reduction in the transport of odorant molecules to the olfactory mucosa, which occurs with head colds, sinus, flu infection or allergies. |
