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

The brain and spinal cord are the parts of the Central Nervous System.

The brain is protected from injuries by a bony box, also known as the cranium or the skull. There is a membranous layer that surrounds the brain (meninges) and is filled with cerebrospinal fluid that acts as shock absorbers protecting the brain.
