Which structure connects the brain and the spinal cord?

• A. Cerebellum
• B. Cerebrum
• C. Hippocampus
• D. Brain stem

Answer: (D)

This question tests which brain structure serves as the bridge between the brain and the spinal cord. The brain stem sits at the base of the brain and is continuous with the spinal cord, acting as the main conduit for all neural signals traveling between the brain and the body. It also houses essential centers that regulate life-sustaining functions such as breathing and heart rate. While the cerebellum, cerebrum, and hippocampus are important for coordination, thought, and memory respectively, they do not provide the direct connection between brain and spinal cord like the brain stem does.
