noun, plural: paranasal sinuses
The paranasal sinuses are lined with mucous membrane that is continuous with the lining of the nasal cavities. Their biological function remains unclear. They are thought to have a role in insulating sensitive structures like dental roots and eyes from rapid temperature changes in the nasal cavity, providing a buffer against blows to the face, increasing the resonance of the voice, or decreasing the relative weight of the front of the skull, and especially the bones of the face.
