Nasal Cavity - Supporting Framework.
Inside the nose, the nasal cavity is framed and supported by several bones and
cartilages.
The nasal cartilages, nasal bones, frontal bone, sphenoid bone, and cribiform
plate of the ethmoid bone support the arched roof of the cavity.
Two pairs of bones form the floor of the cavity. The anterior floor is made up
of the maxilla bones (palatine processes), and the posterior floor is made up
of the palatine bones (horizontal plates). Together, these bones are referred
to as the hard palate.
Three, curved turbinate bones (or nasal conchae) protrude from each lateral wall
into the center of the cavity.
The nasal cavity is divided into left and right chambers called the nasal fossae
the nasal septum. In turn, the thin, vertical, septum is made up of the vomer
bone, the perpendicular plate of the ethmoid bone, and septal cartilage.
