The '''cranial cavity''', or '''intracranial space''', is the space formed inside the [[skull]]. The [[brain]] occupies the cranial cavity, which is lined by the [[meninges]] and which contains fluid to cushion blows.
Eight fused cranial bones together form the cranial cavity: the [[frontal bone|frontal]], [[occipital bone|occipital]], [[sphenoid bone|sphenoid]] and [[ethmoid]] bones, and two each of the [[parietal bone|parietal]] and [[temporal bone|temporal]] bones.<ref name="Martini">Martini R, Ober W, Garrison C, Welch K, and Hutchings RT. 2001.
