Dural Venous Sinuses

Question 1

Dural venous sinuses ultimately drain via the

Answer 1

Internal jugular veins

Question 2

Drainage site of CSF via arachnoid granulations

Answer 2

Superior Sagittal sinus of Dural Venous sinuses

Question 3

Much smaller than the superior sagittal sinus, runs in the inferior concave free border of the falx cerebri and ends at the straight sinus

Answer 3

Inferior sagittal sinus

Question 4

Union of inferior sagittal sinus and great cerebral vein. Runs along attachment between falx cerebri and tentorium cerebelli, and joins the confluence of sinuses

Answer 4

Straight sinus

Question 5

Paired sinus, pass laterally fron confluence of sinuses, form groove in occipital bone, course along posterolateral attachment margins of the tentorium cerebelli and become sigmoid sinuses as they approach posterior aspect of petrous temporal bones

Answer 5

Transverse sinus

Question 6

Continuation of transverse sinuses, forms deep S-shaped grooves in temporal and occipital bones, drains through internal jugular vein

Answer 6

Sigmoid sinus

Question 7

Pool of stagnant blood contained by dural folds. Situated in middle cranial fossa on either side of the body of the sphenoid.

Answer 7
