The Cranial cavity in brief
- The cranial cavity, or intracranial space,
is the space formed inside the skull
- The skull or cranium is a bony structure
serves as the general framework for the head....
- Brain : occupies the cranial cavity,
which is lined by the meninges
The meninges are the system of membranes that
envelop the central nervous system and which
contains fluid to cushion blows.
- Cranial cavity is composed by the frontal,
parietal, sphenoid, temporal and occipital bones,
and in part the ethmoid, all covered by
endosteal layer of dura mater.
- The cranial cavity is divided into
three cranial fossae :
1-Anterior cranial fossa which accommodates
the anterior lobe of brain.
2- Middle cranial fossa, much wider than the
anterior cranial fossa contain the 2 temporal lobes of brain.
3- Posterior cranial fossa is much shallower and
wider than the middle cranial fossa and it
accommodates the occipital lobes of the brain.
