confluence of sinuses

A confluence of sinuses in the skull was originally named torcular Herophili after him.

This term more precisely refers to the concavity in the bone which is the location of the confluence of sinuses.

Near the internal occipital protuberance, it drains into the confluence of sinuses and deviates to either side (usually the right).

It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses.

Right and left transverse sinuses which meet at the confluence of sinuses (marked by the internal occipital protuberance).

They drain from the confluence of sinuses (by the internal occipital protuberance) to the sigmoid sinuses, which ultimately connect to the internal jugular vein.

The confluence of sinuses or torcular herophili is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus.

This vein merges with the inferior sagittal sinus to form the straight sinus which then joins the superficial venous system mentioned above at the confluence of sinuses.

It drains blood from the superior cerebellar veins and inferior sagittal sinus (at the center of the brain) to the confluence of sinuses (at the back of the head by the internal occipital protuberance).

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.

The most prominent of these sinuses is the superior sagittal sinus which flows in the sagittal plane under the midline of the cerebral vault, posteriorly and inferiorly to the torcula, forming the confluence of sinuses, where the superficial drainage joins with the sinus the primarily drains the deep venous system.
