The vomer bone is a thin, unpaired bone located in the center of the nasal cavity. This small, trapezoidal bone is part of the nasal septum, the middle wall of the nasal respiratory cavity.

So thank you, nose hairs. We're now entering the nasal cavity. It's pretty wet because the nose is lined with mucus to keep it moist. And its mucous membranes also warm incoming air. Ahh.
