seperates nose from brain
Nasal Cavity: conchae
located on lateral walls, bits of bone that curl
1) superior
2)middle
3)inferior
helps filter, warm and moisture air by creating turbulent flow
Nasal Cavity: meatus
located under conchae and also helps create turbulent flow
1) superior meatus
2)middle meatus
3) inferior meatus
Nasal Cavity: lateral wall
Cartilage
ethmoid bone (S&M conchae)
inferior concha is it's own wall
Nasal Cavity: medial wall
cartilage
ethmoid bone: superior 1/2 nasal septum
Vomer bone joins with ethmoid
