Origin: [L. See Calvary.]
The calvaria or skullcap is the upper part of the cranium and surrounds the cranial cavity containing the brain. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. The outer surface of the skull possesses a number of landmarks. The point at which the two parietal bones and frontal bones meet is known as "Bregma". The point at which the two parietal and occipital bones meet is known as "Lambda". Not only do these landmarks indicate the fontanelle in newborns, they also act as reference points in medicine and surgery. In the fetus, the formation of the Calvaria involves a process known as intramembranous ossification, although the base of the skull develops through endochondral ossification. 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.
