No, cerebrospinal fluid is not normally found in the sinuses.
The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.

If there were to be an infection in this area, it is possible that you would not receive chemical input from the environment. And for the second portion of your homework... Olfactory cells, olfactory nerve, and olfactory bulb :)

A Freaking Forimina (Lushka and Magendie) Say Back Away! Weird, yes. Memorable? Most definitely.
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
superior sagittal sinus
The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.

paranasal sinus include frontal sinus, the maxillary sinus, the ethmodial sinuses, and the spheniodal sinus.
frontal nasal bone
Yes, the frontal bones contain the frontal sinuses.
Mild mucosal thickening along the left frontal sinus is a sign of sinusitis.
paranasal sinus include frontal sinus, the maxillary sinus, the ethmodial sinuses, and the spheniodal sinus.
Frontal Sinuses.....
If you have a headache just about your eyes, it is very likely that it is your sinuses. Sinus pressure can be very painful.
The maxillae contain the maxillary sinuses, the ethmoid and sphenoid contain the ethmoid and sphenoid sinuses, respectively. ****Maxilla is a facial bone, the three cranial bones that contain sinuses are ethmoid, sphenoid and frontal.
