The superior sagittal sinus, straight sinus, and occipital sinus connect at a series of channels that comprise the confluence of sinuses, which is found beneath the occipital protuberance of the skull. They drain blood into the right and left transverse sinuses.

An older, Latinate term for the confluence of sinuses is torcula herophili.
