The roof of each nasal cavity is formed in its upper third to one half by the nasal bone and more inferiorly by the junctions of the upper lateral cartilage and nasal septum.Connective tissue and skin cover the bony and cartilaginous components of the dorsum of the nose.he nasal cavity (or nasal fossa) is a large air filled space above and behind the nose in the middle of the face. Each cavity is the continuation of one of the two nostrils.
Like the nasal cavity, the sinuses are lined with a mucous membrane composed of cells that produce mucus and have cilia. Incoming dirt particles are trapped by the mucus, and then moved by the cilia into the nasal cavity, through small sinus openings.Because these openings are so small, the drainage can easily be blocked by conditions such as colds or allergies, which produce swelling of the mucous membranes.now 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.
