Fig. 11. Section showing the sagittal plexus in a human embryo 14 mm long

Carnegie Collection, No. 940 (slide 15 row 3. section 1)

The section shows the falciform area, the hemispheres being retracted from its lateral margins. It will be noted that there are two main plexiform vascular sheets — a superficial one near the skin and a deeper one directly against the brain-wall, the latter draining into the former by anastomosing loops. The superior sagittal sinus develops in the meshes of the superficial plexus. and the straight sinus develops in the meshes of the deep plexus over the area corresponding to the third ventricle.
