The nasal septum is the wall of cartilage and bone that divides the nasal cavity into two halves. Deviation or buckling of the septum reduces the air spaces and airflow, causing blockage of the nose and sometimes snoring. Deviation may occur after injury to the nose. If you look up your nose in a mirror under a good light you will also see two red lumps on either side of the septum. These are known as turbinates and also reduce airflow if too large. Turbinates get swollen in a variety of disorders known as rhinitis-hay fever is the most well-known of these problems.
