Final answer:
The inferior nasal conchae extend medially from the lateral walls of the nasal cavity and are considered as paired bones.
Step-by-step explanation:
Relative to the lateral walls of the nasal cavity, the inferior nasal conchae project medially and downwards. These structures are considered paired bones because there is one on each side, making a set of two within the nasal cavity. The inferior nasal conchae significantly enhance the nasal cavity's ability to warm and moisten incoming air.
Unlike the superior and middle conchae, which are part of the ethmoid bone, the inferior nasal conchae are independent bones. Each bone forms a curved bony plate, extending into the space of the nasal cavity from the lower lateral wall. This arrangement helps to increase the surface area for air passage and also aids in trapping particulate matter and humidifying the air we breathe.
