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.
