A long, narrow and curled bone shelf which protrudes into the breathing passage of the nose is called a turbinate, or better known in anatomy as a nasal concha.
the nasal in the middle of the nose
The nasal conchae are made up of the inferior nasal concha and the superior nasal concha, which are part of the ethmoid bone in the skull. They help to increase the surface area within the nasal cavity, aiding in the warming and humidifying of inhaled air.
nasal concha
The inferior nasal concha, a separate bone from the ethmoid bone, forms the most inferior turbinates in the nasal cavity.
Ethmoid
inferior nasal concha
No, it's not.
The scroll-shaped conchae increase the turbulenceof air flowing through the nasal cavity.
The dagger-shaped bone in the nasal cavity is called the vomer bone. It is located in the midline of the nasal cavity and helps to separate the left and right nasal passages.
The inferior nasal concha is part of the maxillary bone, while the middle and superior conchae are part of the ethmoid.
Hypertrophy means overgrowth. The concha are the turbinates, or the ridged parts of the nose that swirl the air for warming and cleaning. Hypertrophy in the turbinates is typically a sign of rhinitis -- often due to allergies. A concha bullosa is a turbinate with air in it; about half of people have one.
I believe it is the "concha"(plural: conchae)
