What is the confluence of sinuses?

The confluence of sinuses is a venous structure formed by the union of the superior sagittal sinus and the straight sinus. Located at the posterior aspect of the skull, it marks the point where these two major cerebral veins meet to drain blood from the brain. The confluence of sinuses plays a crucial role in the cerebral venous drainage system, ensuring the proper circulation and return of deoxygenated blood from the brain back to the heart.
