Nasal cavity

  • The nasal cavity (or cavity of nose, latin: cavum nasi, cavitas nasi) is an initial part of the respiratory tract and lodges the organ of olfaction.

    The nasal cavity is an internal part of the nose, which forms part of the upper air passage. It is an air-filled cavity lined with mucosa. The nasal cavity is formed by the nasal aperture anteriorly, nasal conchae laterally, cribriform plate of the ethmoidal bone superiorly, and palatal processes of the maxilla and horizontal portion of the palatine bone.
