The human brain is well protected by the:
skull.
— Concept: This question tests basic knowledge about the protective structures of the human central nervous system,…Concept: This question tests basic knowledge about the protective structures of the human central nervous system, specifically the brain.
Why (C) is correct: The human brain is a delicate and vital organ. It is encased and protected by the skull (cranium), which is a bony structure forming the head. The skull provides a rigid, protective casing against physical injury.
Why other options are wrong:
- (A) sternum: The sternum (breastbone) protects the heart and lungs, not the brain.
- (B) spinal cord: The spinal cord is part of the central nervous system, extending from the brain, and is protected by the vertebral column, not a protective structure for the brain itself.
- (D) vertebral column: The vertebral column (backbone) protects the spinal cord, not the brain.
Common Mistake: Students might confuse the protective structures for the brain and the spinal cord.
NEET Tip: Remember that the central nervous system (CNS) consists of the brain and spinal cord. The brain is protected by the skull, and the spinal cord is protected by the vertebral column.
Correct Answer: (C)
skull.
