Which phrase identifies the cerebellar layer discussed?

Which phrase identifies the cerebellar layer discussed?

• A. Molecular layer of gray matter of the cerebellum
• B. Purkinje cell layer
• C. Granule cell layer
• D. White matter

Answer: (A)

Think about how the cerebellar cortex is organized into layers. The outermost layer is the molecular layer, which is gray matter and contains the dendrites of Purkinje cells and the parallel fibers from granule cells, along with some interneurons. This makes it the phrase that identifies the cerebellar layer being discussed. The middle layer houses Purkinje cell bodies, the inner granular layer contains granule (and Golgi) cells, and white matter lies beneath the cortex as myelinated axons. So the phrase that best identifies the cerebellar layer discussed is the molecular layer of gray matter of the cerebellum.
