What is the outer layer of the cerebrum?

• A. Cerebral Cortex
• B. Cerebellum
• C. Brain Stem
• D. Limbic System

Answer: (A)

The outer layer of the cerebrum is the cerebral cortex. It’s the sheet of gray matter that covers the surface of the cerebral hemispheres, folded into gyri and sulci to increase surface area for processing. The cortex handles higher-order functions like perception, thinking, language, and voluntary movement. Beneath it lies white matter that carries signals to and from different brain regions. The other structures—cerebellum, brain stem, and limbic system—are not the outer surface of the cerebrum; they have different roles and locations.
