The calvaria (or calva, or skullcap) is the roof of the skull. It is formed by the following bones:
In a fetus, the formation of the skull involves a process known as intramembranous ossification.
[edit] Inner Surface of the Skull-cap
The inner surface of the skull-cap is concave and presents depressions for the convolutions of the cerebrum, together with numerous furrows for the lodgement of branches of the meningeal vessels.
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.
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.
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.
