Know your nose The nasal cavity is divided into two passages by the nasal septum. The nasal septum is composed of both bone and cartilage and extends from the nostrils to the back of the throat. Bones called nasal conchae project into the lateral walls of the nasal cavity, forming a series of folds called turbinates.here are three turbinates on each side of the nasal cavity and are lined by a thick mucous membrane. Turbinates greatly increase the surface area of the nasal cavity. During inhalation air is directed over and under the turbinates. Lining the nasal cavity is a mucous membrane rich with blood vessels.
