Nose and Nasal Cavity | Structure & Functions
Supportive Bones and Cartilages of the Nasal Cavity
Last update:
Posterior to the nose (nose external), is the 
nasal cavity. This large passageway is framed and supported by several bones and cartilages.
- Supporting the arched roof of the cavity are the frontal bone, sphenoid bone, cribriform plate of the ethmoid bone and nasal bones.
- The lateral walls of the cavity are framed by the bodies of the two maxilla bones.

- The cavity floor is supported by the palatine process of the maxilla bones and the horizontal plates of the palatine bones. Together, these bones are referred to as the hard palate.
- A thin vertical plate, the nasal septum, divides the nasal cavity into two chambers (nasal fossae).
- The septum consists of the vomer bone, perpendicular plate of the ethmoid bone, and septal cartilage.

Vestibule Region of the Nasal Cavity
The vestibule is the portion of the nasal cavity that lies directly posterior to the external nares. It is lined by stratified squamous epithelium providing as a barrier that helps protect the vestibule from damage. A layer of mucus typically covers the outer surface of the vibrissae.
Turbinate Bones (Nasal Conchae)
There are three turbinates on each side of the nasal cavity (Superior, middle, and inferior). Grooves are found between the curved turbinates. During inhalation, air is directed over and under the turbinates. The surface mucosa conditions or prepares the air so it can safely travel into the lungs.
Supportive Cartilages and Bones of the Nose
The nose is supported by upper and lower cartilages along with the maxilla and nasal bones. A pair of nasal bones support the bridge of the nose and the medial plates and frontal processes of the maxilla bones support the sides of the nose.
