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.
No one knows what actually causes olfactory receptors to react-it could be a chemical molecule's shape or size or electrical charge. The electrical activity produced in these hair cells is transmitted to the olfactory bulb. The information is then passed on to mitral cells in the olfactory bulb.air 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.
