Question

How is the brain protected in our body?

Hint:

The brain is protected by the skull, meninges, cerebrospinal fluid, and the blood-brain barrier to prevent injury and ensure proper functioning.

Answer 1

Brain Protection:
The brain is one of the most vital organs in the body, and it is protected by several mechanisms:
- The skull, or cranium, is a strong bony structure that encases the brain and protects it from physical trauma and injury.
- The brain is surrounded by three layers of protective membranes called the meninges. These include the dura mater (outer layer), arachnoid mater (middle layer), and pia mater (inner layer).
- The cerebrospinal fluid (CSF), which fills the space between the arachnoid mater and pia mater, cushions the brain and absorbs shocks, preventing sudden movements from causing injury.
- Additionally, the blood-brain barrier protects the brain from harmful substances that may be carried in the blood. Thus, the brain is protected by the skull, meninges, cerebrospinal fluid, and the blood-brain barrier.
