arachnoid granulations within the superior sagittal sinus


     This is an enlarged view of the superior sagittal sinus, taken from Figure 1-16. Since the cut was made exactly in the midline, it has passed through the middle of the sinus - we are inside the sinus looking at the lateral wall, so to speak. The little round balls within the sinus are arachnoid granulations. Admittedly, they are a little hard to see.
