The olfactory epithelium is a layer of odor-sensitive cells located inside the depths of the nose. These cells react to odors as they enter the nose, sending signals to the olfactory bulb.
1 The olfactory segment is lined with a specialized type of pseudostratified columnar epithelium, known as olfactory epithelium, which contains receptors for the sense of the smell. 2  This segment is located in and beneath the mucosa of the roof of each nasal cavity and the medial side of each middle turbinate.nnervation of the nasal cavity responsible for the sense of smell is via the olfactory nerve, which sends microscopic fibers from the olfactory bulb through the cribriform plate to reach the top of the nasal cavity.
