Which statement best describes the location of the transverse sinuses?

• A. They Drain Into the Cavernous Sinus
• B. They Are Located at the Base of the Skull Running Toward the Ears
• C. They Drain Directly Into the Internal Carotid Artery
• D. They Drain Into the Subclavian Veins

Answer: (B)

Transverse sinuses are dural venous channels that sit at the back of the skull and run horizontally from the midline toward the ears. They begin at the confluence of sinuses near the internal occipital protuberance and travel laterally along the inner surface of the skull, along the occipital and temporal bones, toward the mastoid region. This path places them at the base of the skull and toward the ears, before they drain into the sigmoid sinuses and then into the internal jugular veins. They do not drain into cavernous sinus, nor directly into the internal carotid artery, nor into the subclavian veins.
