Structure of Nose
The structure of the nose is a complex design composed of bones, cartilage, and soft tissue. The external structure of the nose is somewhat triangular and is primarily shaped by two bones. The internal structure includes a cavity lined by mucus membrane and hair follicles that keep away foreign particles and humidify the inhaled air.
The nasal cavity is divided by a nasal septum. At the base of the nasal cavity lie the two nostrils that act as an entry to the nose. The nose is mainly innervated by the branches of the trigeminal nerve and olfactory nerve. Blood supply to both the external and internal nose is taken care of by various facial arteries that branch out from the carotids.
