beause it suckes
No one knows exactly what purpose the cranial venous sinuses serve in the skull. The para-nasal sinuses help to add humidity and warmth to the air that is breathed. They also lighten the weight of the skull.
They have two main functions: 1) As in all sinuses, they give size without added weight and 2) They give depth to the voice. You have the para nasal sinuses, assembled around your nose. You have maxillary sinuses, frontal sinuses, ethmoid sinuses and sphenoid sinuses around your nose. These sinuses make the area around your nose, very light in weight. The diagonally opposite part of the skull is thick and heavy. That is occipital bone for example! This has an evolutionary advantage to human being. After deep inspiration, you can float in the water, without any efforts. So these para nasal sinuses has helped you to keep your nose out of water. The opposite thick part of the skull help you in this endeavour. You can very easily understand the importance of your nose in water verses your nose out of water. That is the reason, why the para nasal sinuses are assembled around your nose. All the other advantages are accessory, probably.
Yes. The sinuses are air-filled areas in several bones in the face. They serve to make the skull lighter than if it were made of solid bone.
They are present because if the face was solid bone, the anterior portion of the head would weigh more than the posterior part of the head, making it off balance. The air-filled bones weigh less than solid bone, so the head stays balanced on the neck.
dural sinuses, cerebral sinuses, or cranial sinuses
The sinuses help to lighten the skull, provide resonance to the voice, insulate sensitive structures like the eyes and brain, produce mucus to trap foreign particles, and humidify and filter the air we breathe.
Paranasal sinuses are a group of four air-filled spaces. Maxillary sinuses surround the nasal cavity, frontal sinuses are above the eyes, ethmoid sinuses are between the eyes and sphenoid sinuses are behind the eyes.
To keep you warm.
The paranasal sinuses (which surround the nose) are found in the following bones: frontal, ethmoid, sphenoid, and maxillary. The maxillary sinuses are the largest of all sinuses. There are also sinuses found near the mastoid process of the temporal bone called the mastoid sinuses. The mastoid sinuses communicates with the inner ear, whereas the paranasal sinuses communicate with the nasal cavity.
