It is found deep to the occipital protuberance of the skull. Blood arriving at this point then proceeds to drain into the left and right transverse sinuses. The superior sagittal sinus often drains into (either exclusively or predominantly) one transverse sinus, and the straight sinus drains into the other. An older term often used for the confluence of sinuses "torcular herophili", describes the veins as a gutter, or canal, and honors Herophilos, the Greek anatomist who was the first to use cadavers for the systematic study of anatomy. This term more precisely refers to the concavity in the bone which is the location of the confluence of sinuses.[1] Additional imagesReferences1. ^Tubbs, R.S. Neuroanatomy, 2002:1, 14 External links
