Which pair is most correct for protection of the brain and spinal cord?
Answer and explanation
Correct answer: Skull and vertebral column
The central nervous system needs strong skeletal protection. The brain is enclosed within the skull, while the spinal cord passes through and is protected by the vertebral column, or backbone. Thus option A correctly pairs each nervous-system organ with its protective structure. Ribs mainly protect organs in the chest, and the thigh bone, skin, pancreas, thyroid, and ovary do not form the protective coverings of the brain and spinal cord.
