Introduction:
Paranasal sinuses are a group of air-filled spaces which are surrounded in the nasal cavity. Human possess four paired paranasal sinuses. The maxillary sinus 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.

Answer to Problem 1TYR
Correct answer:
From the list of choice, temporal, is the correct answers, that is option (b)
Explanation of Solution
Justify reasons for the correct statement:
Temporal bone is not the sinus bone, which is situated at the sides and base of the skull
Option (b) is given as temporal
Hence, the correct answer is Option (b) temporal
Justify reasons for the incorrect statements:
Option (a) frontal
Frontal sinuses are located above the eyes, so this is not the correct answer.
Option (c) sphenoid
Sphenoid sinuses are located behind the eyes, so this is not the correct answer.
Option (d) ethmoid
Ethmoid sinuses are located between the eyes, so this is not the correct answer.
Option (e) maxillary
Maxillary sinuses are located under the eyes, so this is not the correct answer.
Hence the option (a), (c), (d) and (e) is incorrect.
