Which structure extends from the lateral wall of the nasal cavity toward the nasal septum?

• A. Inferior nasal concha.
• B. Lateral fossa.
• C. Anterior nasal spine.
• D. Maxillary tuberosity.

Answer: (A)

Inferior nasal concha extends from the lateral wall of the nasal cavity toward the nasal septum. It is one of the nasal turbinates, a separate bone that projects medially into the airway and curves toward the septum, helping to humidify, warm, and filter the air as it flows through the nasal passages. This medial projection creates the inferior meatus beneath it, differentiating it from other nearby structures. The lateral fossa, anterior nasal spine, and maxillary tuberosity are located in other regions and do not extend medially from the lateral nasal wall toward the septum.
