paranasal sinuses









































paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. the maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. the sinuses are named for the facial bones in which they are located.

some of these bones—the occipital, parietal, frontal, in the neurocranium, and the nasal, lacrimal, and vomer, in the facial skeleton are flat bones.









































section::::structure of human skull.:cavities and foramina.









































the skull also contains sinuses, air-filled cavities known as paranasal sinuses, and numerous foramina. the sinuses are lined with respiratory epithelium. their known functions are the lessening of the weight of the skull, the aiding of resonance to the voice and the warming and moistening of the air drawn into the nasal cavity.
