The visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum which consists mostly of cartilage and which separates the nostrils. On average the nose of a male is larger than that of a female.The nose has an area of specialised cells which are responsible for smelling (part of the olfactory system).
