Nose Anatomy: Complete Guide with Parts, Names Diagram It plays a vital role in our sense of smell, making it a key part of the olfactory system Its structure is shaped by the nasal bones and cartilage, including the nasal septum, which separates the nostrils and divides the nasal cavity into two distinct chambers
Nose | Description, Functions, Facts | Britannica nose, the prominent structure between the eyes that serves as the entrance to the respiratory tract and contains the olfactory organ It provides air for respiration, serves the sense of smell, conditions the air by filtering, warming, and moistening it, and cleans itself of foreign debris extracted from inhalations
Introduction to Nose and Sinus Disorders Inside the nose is a hollow cavity (nasal cavity), which is divided into two passages by a thin sheet of cartilage and bone called the nasal septum The bones of the face contain the paranasal sinuses, which are hollow cavities that open into the nasal cavity (see Nose and Sinuses)
Anatomy and Physiology of the Nose and Throat The sinuses are cavities, or air-filled pockets, in the skull and face that drain out through the nasal passages Similar to the nasal passage, the sinuses are lined with mucous membranes
Nose, Nasal Cavities, Paranasal Sinuses - SEER Training Air enters the nasal cavity from the outside through two openings: the nostrils or external nares The openings from the nasal cavity into the pharynx are the internal nares
Nasal cavity - Structure, Function, Anatomy, Diagram The nasal cavity is centrally located within the skull, just behind the external nose It is positioned above the oral cavity, below the cranial cavity, and in front of the nasopharynx
