Olfaction: Anatomy, function, pathophysiology and diseases
The olfactory receptor epithelium functions to transmit odor information from the nose to the brain. Here, we review the anatomy and physiology of the olfactory system. We focus on the organization of the peripheral olfactory apparatus, and the process of transduction of inspired odorant molecules into a neuronal signal. Also, disease processes that cause anosmia are then reviewed. The approach to patients and clinical management of olfactory disorders are discussed.
