It is moulded over the surface of portions of the frontal, parietal, occipital, and temporal lobes of the cerebrum, and displays impressions corresponding to the arrangement of the gyri of these portions of the brain. It also presents a series of well- marked grooves for the lodgment of the venous sinuses which accompany the branches of the middle meningeal artery (F. Wood Jones); these radiate from the sphenoidal angle of the bone, the best marked running upwards at some little distance behind and parallel to its anterior border. Within the superior margin is a series of depressions for arachnoideal granulations, and here also the bone is channelled so as to form a groove (sulcus sagittalis), which is completed by articulation with its fellow of the opposite side. Within this groove lies the superior sagittal venous sinus, and to its edges the falx cerebri is attached. Close to the mastoid angle there is also a curved groove, the transverse sulcus, in which the highest portion or bend of the transverse venous sinus is lodged.

The anterior-rsuperior, and posterior borders are deeply serrated. The anterior border articulates with the frontal bone, forming with it the coronal suture. In the superior part of this suture the frontal bone overlaps the parietal, while the parietal overlies the frontal below. The posterior border is united with the occipital bone to form the lambdoid suture. The superior border articulates with its fellow of the oppos
