Intracranial sinus sinuses

Upper sagittal sinus

Located at the top of the brain hemisphere, it splits longitudinally along the brain, connecting the two brain hemispheres.

Its blood mainly comes from blood-supplying arteries on the surface of the brain, such as the middle cerebral artery and paracerebral veins.

The upper sagittal sinus is one of the main drainage channels of other venous sinuses.

Lower sagittal sinus

Located at the bottom of the brain hemisphere, connected to the bottom of the brain.

Blood is supplied through the middle cerebral artery and the basement cerebral artery.

The inferior sagittal sinus is one of the important channels for intracranial venous return.

Straight sinus

Located behind the brain stem, it extends to the center of the brain.

It is mainly composed of venous blood from the brain and trunk.

It plays a role in draining blood in the internal cerebral venous blood.

Short sinus

Located at the base of the skull, it is responsible for draining blood from the base of the skull.

Connect the basal cerebral artery to the cavernous sinus.

Cavernous sinus

Located at the base of the skull, it has a reticular structure.

Receive venous blood from short sinuses, cerebral veins, orbits, sinuses, etc.

It plays an important role in intracranial venous return.

Sigmoid sinus

Located at the base of the skull, it runs along the centerline of the brain.

It is an important connection channel between the cerebral vein and the ventricle system.

It plays the function of venous return within the brain.

Transverse sinus

Located on the side of the base of the skull, it crosses between the rock cone and the rock slope.

Drain venous blood in areas such as rock cones, rock slopes, etc.

Sigmoid sinus

Located at the base of the skull, it runs along the centerline of the brain.

It is an important connection channel between the cerebral vein and the ventricle system.

It plays the function of venous return within the brain.

Transverse sinus

Located on the side of the base of the skull, it crosses between the rock cone and the rock slope.

Drain venous blood in areas such as rock cones, rock slopes, etc.

Rock venous sinus

Located in the bone rock (rock part), it has a special anatomical structure.

Connect to the cavernous sinus through the rock part in the skull.

It acts to drain venous blood in the structures around the inner ear and inner ear.

Long straight sinus

Located at the posterior part of the skull base and extends along the basal part.

Connect the basal artery and cerebral veins blood.

It plays an important role in venous return.

The complex network structure of various sinuses in the cranial venous sinuses ensures the blood supply and excretion function of brain tissue, which is crucial to maintaining the normal function of the brain.
