Rodgersia

The sagittal sulcus is a midline groove that runs across the internal surfaces of part of the squamous part of the frontal bone, the parietal bones,^[1] and part of^{[citation needed]} the occipital bones. The sagittal sulcus accommodates the superior sagittal sinus. The falx cerebri attaches to the edge of the sagittal sulcus^[1] on either side.^{[citation needed]}

On the inferior portion of the squamous part of the frontal bone, the edges of the sagittal sinus converge to form a single midline ridge, the frontal crest (which also gives attachment to the falx cerebri).^[1]
