conchae or turbinate bones. These extend out from the
lateral wall of the cavity and almost reach the nasal septum.
The cavity is subdivided into a series of narrow
passageways called the superior meatus (soo-PEER-ih-
or mee-AY-tus), middle meatus, and inferior meatus.
Mucous membranes line the cavity and those shelves.
Olfactory receptors are located in the membrane that
lines the superior meatus; this area is called the olfactory
region. Below, the membrane consists of pseudostratified,
ciliated, columnar epithelial cells with many goblet cells
that produce mucus. Blood capillaries are also found here.
