Components of the Nose. The nose is composed of a skeleton covered by âthe skin-soft tissue envelopeâ. The skeleton is composed of several bones and cartilages of different shape connected together. Another very important component of the skeleton, which is inside the nose, is the nasal septum.
Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face and serves as an alternative respiratory passage especially during suckling for infants. On most other mammals, it is located on the upper tip of the snout.
