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 cranial bones together form the cranial cavity: the frontal and occipital bones, and two each of the parietal, temporal, sphenoid and ethmoid bones.^[1]

The capacity of an adult human cranial cavity is 1,200-1,700 cm³.^[2]
