Severe injury to the soft structures within the skull may follow head trauma. What structures exist within the skull to limit damage to the cerebral hemispheres and other parts of the brain? Which blood vessels are damaged more commonly, the cerebral arteries or the cerebral veins? Which cranial nerves are likely to be damaged in head injuries? What is the reason for their susceptibility?

The Answer is The meninges and the cerebrospinal fluid afford a remarkable degree of protection to the brain tissue. The dural partitions limit the extent of side-to-side, forward and backward, and rotation movements of the brain within the skull.
The thin-walled cerebral veins are liable to be damaged during excessive movements of the brain relative to the skull, especially at the point where the veins join the dural venous sinuses. The thick-walled cerebral arteries are rarely damaged.
The small-diameter cranial nerves of long length are particularly prone to damage during head injuries. The trochlear, abducent, and oculomotor nerves are commonly injured.
