tentorial sinus
An unpaired venous dural sinus that receives blood from the superior cerebellar veins and inferior sagittal sinus and drains into the confluence of sinuses. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the tentorial sinus is
An unpaired venous dural sinus that receives blood from the superior cerebellar veins and inferior sagittal sinus and drains into the confluence of sinuses. The atlas records it as a organ at the organ scale in the human body.
Where the tentorial sinus is
It sits within the cardiovascular and nervous systems. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What the tentorial sinus connects to
The atlas records 4 typed relationships for it, across 3 kinds of connection. a kind of unpaired venous dural sinus.
Supply and innervation
Venous drainage: inferior sagittal sinus.
Also called
Also recorded as rectus sinus, sinus rectus, straight sinus and straight sinus vein. Searching any of those names reaches this page.

Questions
Where is the tentorial sinus?
It sits within the cardiovascular and nervous systems. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What does the tentorial sinus connect to?
A kind of: unpaired venous dural sinus.
Is the tentorial sinus the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
