The Bio Brief

The brain and spinal cord are very delicate and important organs.
So, our body provides them with strong protection.

Protection of the Brain

1. Skull (Cranium)

• The brain is placed inside a hard bony box called the skull.
• It protects the brain from external injuries.

2. Cerebrospinal Fluid (CSF)

• Inside the skull, the brain is surrounded by a fluid-filled covering.
• This fluid acts as a shock absorber.
• It protects the brain from sudden jerks and shocks.

Protection of the Spinal Cord

• The spinal cord runs through the vertebral column (backbone).
• The backbone is made of many small bones called vertebrae.
• These bones form a protective canal around the spinal cord.

 When you touch the middle of your back, the hard, bumpy structure you feel is the vertebral column.

Why Is Protection Necessary?

• The brain controls thinking, movement, and life processes
• The spinal cord carries messages to and from the brain
• Damage to these tissues can be very dangerous

Key Points to Remember

• Brain is protected by skull and cerebrospinal fluid
• Spinal cord is protected by the vertebral column
• These protections prevent injury and shock
