In which area of the skull is the nasal septum located?

The nasal septum is located in the facial skeleton, which is a part of the skull specifically composed of the bones that structure the face. It separates the left and right nasal passages and is primarily formed by the perpendicular plate of the ethmoid bone and the vomer bone. This anatomical arrangement is crucial for proper airflow and nasal function.

The other options, while they refer to different regions of the skull, do not pertain to the location of the nasal septum. The occipital region refers to the back portion of the skull, the cranial cavity houses the brain and does not include facial structures like the nasal septum, and the area between the temporal bones does not encompass the nasal septum either, as it is lower down in the facial region. Thus, identifying the nasal septum as situated within the facial skeleton is essential for understanding its role in both anatomy and respiratory function.
