Paranasal sinuses are filled with air
Their function is to-
- humidify and warm the inspired air,
- provide resonance to voice,
- lighten the skull bones, and
- act as thermal insulators to protect orbit and cranium from variation in temperature of air in our nose
Paranasal sinuses are air containing cavities (hollow spaces) in certain bones of skull. They are 4 on each side, they are- maxillary, frontal, sphenoid and anterrior and posterior ethmoidal sinuses.
They are spaces within the bones, hence their walls are formed by bones, which are lined from inside by very thin mucous membrane (ciliated columnar epithilium with goblet cells) (goblet cells secrete mucus and the cilia move it out of the sinus into the nasal cavity)
They all open into the nasal cavity.

Do paranasal sinuses open into the oral cavity?
No, paranasal sinuses do not open directly into the oral cavity. They are connected to the nasal cavity and help to warm, humidify, and filter the air we breathe. The oral cavity is separate and has its own openings for the passage of air, food, and saliva.
Is sinusitis an infection of the nasal cavity?

paranasal sinus include frontal sinus, the maxillary sinus, the ethmodial sinuses, and the spheniodal sinus.
What are the four pairs of paranasal sinuses?
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.
What is thought to lighten the head and provide resonancefor the voice?
The sinuses: paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity (maxillary sinuses), above the eyes (frontal sinuses), between the eyes (ethmoidal sinuses), and behind the ethmoids (sphenoidal sinuses).
What bones are paranasal sinuses?
The bones that contain the paranasal sinuses are the maxillary, frontal, ethmoid, and sphenoid bones. They are easy to remember in relation to the sinuses because each sinus has the same name as the bone it is in.

Are Sinuses found in the temporal bone?
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.
What bone does not contain paranasal sinuses?
