Within the dura mater - the dural venous sinuses lie between the periosteal & meningeal layers. The scalp, face and CNS are all drained into this system of sinuses. These sinuses are unique however as they do not contain valves! @rev.med ✅ Venous Sinuses These valveless veins are 11 in total. The straight, superior, and inferior sagittal sinuses are found in the falx cerebri of the dura mater. They meet at the confluence of sinuses. The straight sinus is a continuation of the great cerebral vein of Galen and the inferior sagittal sinus. From the confluence, the transverse sinus continues bi-laterally and curves into the sigmoid sinus to meet the opening of the internal jugular vein. @rev.med The cavernous sinus drains the ophthalmic veins and can be found on either side of the sella turcica. From here, the blood returns to the internal jugular vein via the superior or inferior petrosal sinuses. 👀 Critical stuff to know! Sketch out just the sinuses on a paper and label it, repeat till you get it! Much more coming soon, stay focused, keep at it, and don’t give up no matter what! @rev.med @rev.med #venoussinuses #REVMED #REVupyourbrain #revmedicine https://www.instagram.com/p/CSe4BTLLWos/?utm_medium=tumblr
