The image shows a dissected medial view of the right hemisphere, with the nose and frontal lobe towards the left of the image, and the occipital lobe and the cerebellum towards the right of the image. The superior sagittal sinus is the largest dural venous sinus which arises in between the layers of the dura mater immediately superior to the falx cerebri and which travels in the midline between the two cerebral hemispheres. However, the blue arrow indicates the straight sinus, which is a dural venous sinus formed by the union of the inferior sagittal sinus and the great cerebral vein of Galen, and which travels in between the dural layers at the level between the falx cerebri and the tentorium cerebelli.

Superior sagittal sinus
QuestionChoice
The image shows a dissected medial view of the right hemisphere, with the nose and frontal lobe towards the left of the image, and the occipital lobe and the cerebellum towards the right of the image. The inferior sagittal sinus is a dural venous sinus located in the inferior edge of the falx cerebri, immediately superior to the corpus callosum. It unites with the great cerebral vein of Galen located inferiorly, to form the structure indicated by the blue arrow which is the straight sinus. The straight sinus is a dural venous sinus formed by the union of the inferior sagittal sinus and the great cerebral vein of Galen, and it travels in between the dural layers at the level between the falx cerebri and the tentorium cerebelli.

b
Inferior sagittal sinus
QuestionChoice
The image shows a dissected medial view of the right hemisphere, with the nose and frontal lobe towards the left of the image, and the occipital lobe and the cerebellum towards the right of the image. The blue arrow indicates the straight sinus, which is a dural venous sinus formed by the union of the inferior sagittal sinus and the great cerebral vein of Galen. It terminates at the confluence of sinuses, together with the superior sagittal sinus and the two transverse sinuses. The straight sinus travels in between the dural layers at the level between the falx cerebri and the tentorium cerebelli.

a
Straight sinus
QuestionChoice
The image shows a dissected medial view of the right hemisphere, with the nose and frontal lobe towards the left of the image, and the occipital lobe and the cerebellum towards the right of the image. The great cerebral vein of Galen is a large vein, which drains the deep aspects of the brain. It unites with the inferior sagittal sinus, located superior to it and forms the structure indicated by the blue arrow, the straight sinus, which travels in between the dural layers at the level between the falx cerebri and the tentorium cerebelli.

d
Great cerebral vein of Galen
QuestionChoice
The image shows a dissected medial view of the right hemisphere, with the nose and frontal lobe towards the left of the image, and the occipital lobe and the cerebellum towards the right of the image. The transverse sinuses are paired dural sinuses, travelling in the dural layers of the tentorium cerebelli, connecting the sigmoid sinuses laterally with the confluence of sinuses in the midline. The blue arrow indicates the straight sinus, which is a dural venous sinus formed by the union of the inferior sagittal sinus and the great cerebral vein of Galen. It travels in between the dural layers at the level between the falx cerebri and the tentorium cerebelli.
