|
Cavernous sinus:
-covered by the meningeal layer of dura, lying against the body of the sphenoid just lateral to the sella turcica. Receives blood from the orbit, via the inferior and superior opthalmic veins, from the pterygoid plexus and from the brain via cerebral veins. it is drained by superior and inferior petrosal sinuses. CN # and ... lie in the sinus. CNs ...... are in the lateral wall. Infection here will lead to problems with eye muscles. hallmark symptom is opthalmoplegia |
