The brain is contained within which part of the central nervous system?

Spinal cord
Cranium
Pelvis
Thorax

The correct answer is: Cranium

The brain is contained within the cranium, which is the bony structure that forms the protective casing for the brain in the skull. This inherited anatomy functions to shield the delicate tissues of the brain from physical damage and injury. The cranium also provides the necessary environment for the brain to maintain its structure and support its intricate functions. The other choices do not serve as protective areas for the brain. The spinal cord is a part of the central nervous system but runs within the vertebral column, separate from the brain. The pelvis and thorax are anatomical regions that house other organs and systems, but they do not contain the brain. Thus, the cranium is the definitive area within the central nervous system that encases and protects the brain, making it the correct answer.
