Verified step by step guidance

Understand the anatomy of the nasal cavity: The nasal cavity is a hollow space within the nose that is divided into two halves by the nasal septum. It has lateral walls, a roof, and a floor, each containing specific structures.

Identify the function of the nasal conchae: The nasal conchae (also called turbinates) are curved bony structures that extend from the lateral walls of the nasal cavity. They help increase the surface area for air filtration, humidification, and warming.

Differentiate the listed structures: The nasal septum divides the nasal cavity into left and right halves, the hard palate forms the floor of the nasal cavity, and the cribriform plate is part of the ethmoid bone forming the roof of the nasal cavity. None of these extend from the lateral walls.

Focus on the lateral walls: The lateral walls of the nasal cavity contain the superior, middle, and inferior nasal conchae, which are responsible for creating turbulence in the airflow and aiding in respiratory functions.

Conclude that the correct answer is nasal conchae: Based on the anatomical location and function, the nasal conchae are the structures that extend from the lateral walls of the nasal cavity.
