How are nervous organs protected?

How are nervous organs Protected?

• Brain is a delicate organ required for all processes and actions in our body and is therefore a very important organ.
• If nerves are damaged, then performing basic functions like moving our hands, walking etc will be very difficult. 
• The nerves can't regenerate their neurons to fix themselves if damaged, thus need to be protected.

• • The brain is placed in a bony box called cranium and is a part of the skull.

Inside the brain box there is a fluid-filled balloon that acts as a shock absorber/ spring/ cushion called meninges .

• • The fluid is called the cerebrospinal fluid .
  • The spinal cord is protected by the vertebral column or backbone .
  • The vertebral column is formed by 33 individual bones called vertebrae

You can feel your backbone if you run your hand down the middle of your back.
