'Brain and spinal cord are two vital organs of our body'. How is our body designed to protect them?

(N/A) The brain is protected by a bony box called the cranium (skull),which provides a hard outer covering. Inside the skull,the brain is cushioned by a fluid-filled balloon known as the cerebrospinal fluid $(CSF)$,which absorbs mechanical shocks and protects the brain from injury.
The spinal cord is protected by the vertebral column (backbone),which provides structural support and shields it from physical damage.
Additionally,both the brain and the spinal cord are covered by three protective membranes known as the meninges,which provide further insulation and protection.
