Detailed explanation-1: -The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
Detailed explanation-2: -The two regions of the skull are the cranial and facial region. The cranial portion is the part of the skull that directly houses the brain and the facial portion includes the rest of the bones of the skull.
Detailed explanation-3: -Your brain and spinal cord are protected and supported by three meningeal layers. These membrane layers are the dura mater, arachnoid mater and pia mater. The layers plus cerebrospinal fluid keep your brain tissue from jostling against your skull, as well as other functions.
