Along the middle line is a longitudinal groove, narrow in front, where it commences at the frontal crest, but broader behind; it lodges the superior sagittal sinus, and its margins afford attachment to the falx cerebri. The falx cerebri (Latin: scythe of the brain) is an extension of the protective dura mater that projects into the longitudinal fissure that seperates the two cerebral hemispheres. ...
On either side of it are several depressions for the arachnoid granulations, and at its back part, the openings of the parietal foramina when these are present. Arachnoid granulations (and arachnoid villi) are small protrusions of the arachnoid (the thin second layer covering the brain) through the dura (the thick outer layer). ...
At the back part of the parietal bone and close to the upper or sagittal border is the parietal foramen, which transmits a vein to the superior sagittal sinus, and sometimes a small branch of the occipital artery; it is not constantly present, and its size varies considerably. ...
It is crossed, in front, by the coronal suture, and behind by the lambdoidal, while the sagittal lies in the medial plane between the parietal bones. The coronal suture (sutura coronalis) is a dense, fibrous connective tissue joint that separates the frontal and parietal bones of the skull. ...
