Beginner Dural Venous Sinuses Quiz

Q1. Where are the dural venous sinuses located?

• Inside the cerebral ventricles
• Between the skull and scalp
• Within the pia mater
• Between layers of cranial dura mater

Q2. What is a characteristic feature of most dural venous sinuses?

• They are lined by ependyma
• They lack conventional venous valves
• They carry only arterial blood
• They contain thick smooth muscle walls

Q3. Which sinus runs along the attached superior margin of the falx cerebri?

• Superior petrosal sinus
• Superior sagittal sinus
• Straight sinus
• Inferior sagittal sinus

Q4. Which sinus runs in the free inferior margin of the falx cerebri?

• Cavernous sinus
• Sigmoid sinus
• Inferior sagittal sinus
• Occipital sinus

Q5. Which sinus receives the inferior sagittal sinus and great cerebral vein?

• Straight sinus
• Superior sagittal sinus
• Sphenoparietal sinus
• Inferior petrosal sinus

Q6. What is the confluence of sinuses?

• A junction where major dural venous sinuses communicate
• A subarachnoid cistern
• A cluster of cerebral arteries
• The opening of the cerebral aqueduct

Q7. Which sinus continues from the transverse sinus toward the jugular foramen?

• Straight sinus
• Cavernous sinus
• Sigmoid sinus
• Superior sagittal sinus

Q8. The sigmoid sinus continues as which major vein after leaving the skull?

• External jugular vein
• Internal jugular vein
• Facial vein
• Vertebral artery

Q9. Which paired dural sinus lies on either side of the body of the sphenoid bone?

• Straight sinus
• Superior sagittal sinus
• Occipital sinus
• Cavernous sinus

Q10. What type of blood do dural venous sinuses primarily drain?

• Venous blood from intracranial and cranial structures
• Only lymph from the scalp
• Only cerebrospinal fluid
• Oxygenated blood directly from the aorta
