âOlfactory ciliaâ is a fancy way of saying ânose hairs,â but is important to distinguish between the macroscopic nose hairs near the opening of the nostrils, and the microscopic hairs in the olfactory epithelium, the part of the nose which traps smells and communicates them to the brain.d. The olfactory cilia inside the nose line the mucus membranes of the nose, and unlike most other cilia in the body, they are non-motile, remaining stationary in the nose rather than wiggling around in the mucus like the cilia which line the trachea and intestines do.
In humans, the olfactory epithelium is located about 7 cm up and into the nose from the nostrils. The Olfactory System. 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.n humans, the olfactory epithelium is located about 7 cm up and into the nose from the nostrils.
