Answers

The largest sinus cavity is B. Maxillary Sinus

The answer is D  cavernous sinus

Explanation:

The cavernous sinus is the venous structure involved in this process; which is made up of a group of facial veins that form a cavity limited by the efenoid. It contains inside the internal carotid artery and the VI cranial nerve or external ocular motor.

The maxillary sinus, that is, the sinus located in the upper jaw, would be affected.

Explanation:

Sinusitis is a very traditional disease that is associated with headache, discomfort, and increased mucus making.

The causes can be viral or bacterial or even by some inhaled noxa, sinusitis of this type is bilateral, different from sinusitis of dental cause that are usually unilateral.

The paranasal sinuses are the sinuses that pneumatize the head, that is, they generate an internal air current in the bones to be able to heat and disinfect them from those noxas that are inhaled (that is why they are covered by a ciliated mucosa that drags the noxa to the outside and also its structure is pseostratified with mucous cells that secrete mucus enveloping the noxa).

Another function of the paranasal sinuses is to be able to alleviate the weight of the head, since the shell and the bones that remain in the head formation are very heavy, thus generating these cavities filled with air to alleviate the feeling of "heavy head" "When they become inflamed and filled with mucus, they are obliterated or with a reduced space, so the head feels heavier for some people.

The paranasal sinuses are the maxillary sinuses that are in the upper jaw, the sphenoid sinuses that are in the sphenoid, the ethmoid sinuses that are in the ethmoid and the frontal ones that are in the frontal bone that is vulgarly called as the forehead.

Frontal: paranasel ! Hope this helps
