The gray matter region in the cerebellum is which?

The gray matter region in the cerebellum is which?

• A. White matter of cerebellum
• B. Gray matter of cerebrum
• C. Gray matter of cerebellum
• D. White matter of cerebrum

Answer: (C)

Gray matter is where neuron cell bodies reside. In the cerebellum, this material forms the cerebellar cortex—the outer gray layer that sits atop the white matter. The cortex contains the cellular circuitry that processes inputs and coordinates output, while the white matter below (the arbor vitae) is made of myelinated axons connecting the cortex to other brain regions. There are also gray matter clusters called deep cerebellar nuclei embedded within the white matter, but the organized gray region you’re identifying in the cerebellum is the cerebellar cortex. So, the gray matter region of the cerebellum is the cerebellar cortex.
