Difference between Cerebrum and Cerebellum

The cerebrum consists of two cerebral hemisphere joined by a curved thick band of nerve fibres, called corpus callosum. The outer layer of the cerebrum , known as cerebral cortex , is formed of grey matter and white matter. The cerebellum is similar to cerebrum  in that it has two hemispheres and has a highly folded surface or cortex. The cerebellum is the second largest part of the brain, and is located at the back of the skull.
