The widespread influence of olfaction

The full importance of olfaction has received minimal attention until recently renewed interest reveals that it becomes necessary not only for protection but also for digestion, memory, emotions, motor skills, and sexual performance. By reviewing the interrelationship of olfactory anatomical structures with the brain, examining precipitating factors contributing to olfactory disorders and recognizing the resulting pathophysiological conditions, nursing can contribute to future research by documenting systemic assessments which pay particular attention to the history of olfactory dysfunction.
