Exploration of the meninges and brain in situ
Dura removed, arachnoid membrane intact, cerebral veins and cortical arteries
The dura mater has been cut away so that the left cerebral hemisphere is visible lying inside the arachnoid membrane. The tentorium appears in the lower right part of the view and the transverse sinus is opened along its posterior border. The superior sagittal sinus has been opened by removing a strip of dura from its superficial wall. The superior cerebral veins ascend on the surface of the frontal and parietal lobes to empty into this sinus at various points. A number of anastomoses are present between these veins, none being particularly large in this specimen. In general the superior cerebral veins are divided into anterior and posterior groups. In this case there appear to be several anterior vessels, a group of large veins intermediate in position (overlying the region of the central sulcus) and several posterior veins (not visible in this view).
