17. olafactory nerves are found in the roof of NASAL CAVITY-answer 40. the brains straight sinus permits immediate CSF drainage from the cavernous sinuses -answer petrosal sinuses Superior sagittal sinus inferior sagittal sinus The olfactory nerve is tactile in nature and begins on the olfactory mucosa in the upper part of the nasal hole. From the olfactory mucosa, the nerve (really numerous little nerve fascicles) goes up through the cribriform plate of the ethmoid issue that remains to be worked out the surface of the cerebrum. ============================================== The cavernous sinus is a vital structure in light of its area and its substance which incorporate the third cranial (oculomotor) nerve, the fourth cranial (trochlear) nerve, parts 1 (the ophthalmic nerve) and 2 (the maxillary nerve) of the fifth cranial (trigeminal) nerve, and the 6th cranial (abducens) nerve.
