The confluence of sinuses or torcular herophili is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus. It is found beneath the occipital protuberance of the skull. Blood arriving at this point then proceeds to drain into the left and right transverse sinus. Interestingly, oftentimes the superior sagittal sinus drains into (either exclusively or predominantly) one transverse sinus, and the occipital sinus drains into the other.
