Detailed explanation-1: -The word “sinus” is most commonly understood to be the paranasal sinuses that are located near the nose and connect to the nasal cavity. There are four paranasal sinuses, each corresponding with the respective bone from which it takes its name: maxillary, ethmoid, sphenoid, and frontal.
Detailed explanation-2: -Your cheekbones hold your maxillary sinuses (the largest). The low-center of your forehead is where your frontal sinuses are located. Between your eyes are your ethmoid sinuses. In bones behind your nose are your sphenoid sinuses.
Detailed explanation-3: -Sinuses are interconnected cavities in the skull. These cavities are linked to your nasal passages by small channels. The channels let air flow from your nose into the sinuses and allow mucus to drain from every sinus into the nose.
Detailed explanation-4: -The nasal cavity is the air-filled compartment above the palate, bordered by skeletal structures and cartilages, and covered from inside by mucosa.
