Frontal Sinus:The size and shape of the frontal sinus can vary from person to person. These spaces fill up with mucus, which then drain into the nose.
Nasal Bone:The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the nose.
Septal Cartilage of Nose:Completes the separation between the nasal cavities in front.
Greater Alar Cartilage:A flexible cartilage that forms part of the structure of the nostrils.
Nasal Concha:They increase the surface area of these cavities, thus providing for rapid warming and humidification of air as it passes to the lungs.
Sephenodial Sinus:Air-filled sacs (empty spaces) on either side of the nasal cavity that filter and clean the air breathed through the nose and lighten the bones of the skull.
Nasopharynx:It provides a major drainage path for lymphatic fluids and generally drains into the throat, nose or ears.
Eustachian Tube:The canal that connects the middle ear to the upper throat and the back of the nasal cavity.Controls the pressure within the middle ear, making it equal with the air pressure outside the body.
Maxilla:The jaw or jawbone, specifically the upper jaw in most vertebrates. In humans it also forms part of the nose and eye socket.
Hard Palate: It is immobile, It forms the anterior aspect of the palate.
Soft Palate: It is mobile, and comprised of muscle fibres covered by a mucous membrane.
