1AnswerB·
Concept: This question tests your knowledge of the protective coverings of the brain, specifically the meninges.
Why (B) is correct: The brain and spinal cord are protected by three layers of connective tissue called the meninges. From outermost to innermost, these layers are the dura mater, arachnoid mater, and pia mater. Therefore, the dura mater is the outermost covering.
Why other options are wrong:
- (A) pia mater: This is the innermost layer of the meninges, closely adhering to the brain's surface.
- (C) corpus callosum: This is a large, thick nerve tract that connects the two cerebral hemispheres, not a covering.
- (D) arachnoid: This is the middle layer of the meninges, located between the dura mater and pia mater.
NEET Tip / Mnemonic: To remember the order of meninges from outermost to innermost, think of the mnemonic DAP: Dura mater, Arachnoid mater, Pia mater.
Correct Answer: (B)
dura mater.
