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.
Hair cells are the receptors in the olfactory epithelium that respond to particular chemicals. These cells have small hairs called cilia on one side and an axon on the other side. In humans, there are about 40 million olfactory receptors; in the German Shepherd dog, there are about 2 billion olfactory receptors.air cells are the receptors in the olfactory epithelium that respond to particular chemicals.
