The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system . The shape of the nose is determined by the nasal bones and the nasal cartilages , including the nasal septum , which separates the nostrils and divides the nasal cavity into two.
The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
Nasal cavity. The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal ...
52745. Anatomical terms of bone. [ edit on Wikidata] 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 upper one third of the nose . Each has two surfaces and four borders.
Illustration of upper respiratory system. In anatomy, a nasal concha ( / ˈkɒnkə /; pl.: conchae; / ˈkɒnkiː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals.
Nasal bridge. Nasal bridge is the bony part of the nose, overlying the nasal bones, above the part in blue labeled "Cartilage of Septum". The bridge is between the eyes, and just below them. The lower half of the nose is below the bridge. The nasal bridge is the upper, bony part of the nose, which overlies the nasal bones .
The inferior nasal conchae are considered a pair of facial bones. As the air passes through the turbinates, the air is churned against these mucosa-lined bones in order to receive warmth, moisture and cleansing. Superior to inferior nasal concha are the middle nasal concha and superior nasal concha which both arise from the ethmoid bone, of the ...
Nasal meatus. In anatomy, the term nasal meatus [1] can refer to any of the three meatuses (passages) through the skull ' s nasal cavity: the superior meatus ( meatus nasi superior ), middle meatus ( meatus nasi medius ), and inferior meatus ( meatus nasi inferior ). The nasal meatuses are the spaces beneath each of the corresponding nasal conchae.
Frontal sinus. Outline of bones of face, showing position of air sinuses. Frontal sinus is shown in green. The frontal sinuses are one of the four pairs of paranasal sinuses that are situated behind the brow ridges. Sinuses are mucosa -lined airspaces within the bones of the face and skull.
