Model Answer
(a) The brain is protected by a bony box (cranium/skull). Inside the skull, the brain is enclosed in a fluid-filled balloon which provides shock absorption. The spinal cord is protected by the vertebral column.
(b) The region responsible is the hind-brain. The specific part is the cerebellum, which is responsible for maintaining posture and balance of the body.

Explanation
- For part (a), mention both layers of protection — the bony skull AND the fluid-filled balloon — to score full marks. Many students forget the fluid-filled balloon.
- For part (b), examiners expect both the region (hind-brain) and the specific part (cerebellum). Writing only one will cost you marks. The exact NCERT phrase "posture and balance" should be used.
