{"product_id":"9786137138717","title":"Cavernous Sinus","description":"Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The cavernous sinus (or lateral sellar compartment), within the human head, is a large collection of thin-walled veins creating a cavity bordered by the temporal bone of the skull and the sphenoid bone, lateral to the sella turcica. The sinus may be joined by several anastomoses across the midline. The cavernous sinus receives blood via the ophthalmic vein through the superior orbital fissure and from superficial cortical veins, and is connected to the basilar plexus of veins posteriorly. The internal carotid artery (carotid siphon), and cranial nerves III, IV, V1, V2 and VI all pass through this blood filled space. Infection from the face may reach the cavernous sinus through its many anastomotic connections, with severe consequences. The cavernous sinus drains by two channels, the superior and inferior petrosal sinuses, ultimately into the internal jugular vein.","brand":"Flu Press","offers":[{"title":"Default Title","offer_id":47040912916720,"sku":"9786137138717","price":37.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9786137138717_p0.jpg?v=1763721990","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9786137138717","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
