Which bone protects the brain?

✅ Correct Answer: C — Skull (Cranium)

The Skull (Cranium) is the bony structure that encases and protects the brain from external injuries. The cranium consists of 8 cranial bones fused together at immovable joints called sutures. The total human skull has 22 bones (8 cranial + 14 facial bones). It also protects the sense organs (eyes, ears, nose).

❌ Why other options are wrong:

• A. Vertebra — Vertebrae form the spinal column (backbone) and protect the spinal cord, not the brain.

• B. Sternum — Sternum (breastbone) is the flat bone in the chest that protects the heart and lungs, not the brain.

• D. Rib — Ribs form the rib cage that protects the heart and lungs; they have no role in brain protection.

📝 Important Note: Skull has 22 bones: 8 cranial (protect brain) + 14 facial. The spinal cord is protected by 33 vertebrae. Heart & lungs are protected by 12 pairs of ribs + sternum. Human skeleton has 206 bones. Cranium = braincase. SSC CGL frequently asks body protection questions.
