Trauma to the Olfactory Nerves
This exhibit depicts permanent damage to the olfactory nerves as a result of head trauma. Normal olfactory nerves travel through perforations in the cribriform plate, into the nasal cavity, and provide a sense of smell. Head trauma, resulting in subdural hemorrhaging and edema, causes the olfactory nerves to be severed. This leads to permanent hyposmia (decrease in the sense of smell).
