Which dural venous sinus is described as a paired vessel located on the inside of the base of the skull running toward the ears?

• A. Inferior Sagittal Sinus
• B. Straight Sinus
• C. Superior Sagittal Sinus
• D. Transverse Sinuses

Answer: (D)

Dural venous sinuses are channels formed by the folds of the dura mater that drain venous blood from the brain. The description fits the transverse sinuses: two paired channels located along the inner surface at the base of the skull, running laterally from the confluence of sinuses toward the temporal region and toward the ears, where they continue as the sigmoid sinuses en route to the internal jugular veins. They are distinct from midline sinuses like the superior and inferior sagittal sinuses, which run along the falx cerebri rather than toward the ears.
