=====Calvaria=====
The [[calvaria]] or skullcap (feminine Latin noun with plural calvariae; however many medical texts list the word as "[[calvarium]]"

The calvaria ([[skull]] cap) is made up of the superior portions of the [[frontal bone]], [[occipital bone]], and [[parietal bone]]s.

The outer surface of the skull possesses a number of [[landmark]]s. The point at which the frontal bone and the two parietal 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.

[[Intracranial pressure]] (ICP) is pressure inside the bony calvarium and therefore reflects the pressure of the [[brain parenchyma]] and [[cerebrospinal fluid]] (CSF). The [[Monro-Kellie hypothesis]] operates under the assumption that the [[cranium]] is incompressible and the volume inside the cranium is fixed
