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.
Smelling and the Nose. We use our nose to smell things. At the top of the inside of our nose are millions of tiny little hairs called cilia. These hairs are connected to smell sensors which send signals to our brain about smell via the olfactory nerve. We smell things when they emit small molecules that float in the air and end up in our nose. We can't see these tiny molecules, but they are there.
