the arbor vitae refers to ______.

○ the pleatlike convolutions of the cerebellum
○ cerebellar gray matter
○ cerebellar white matter
○ flocculonodular nodes

Explanation:

To solve this, we recall the anatomy of the cerebellum. The arbor vitae (Latin for "tree of life") is the white matter of the cerebellum, which has a branched, tree - like appearance due to the arrangement of myelinated nerve fibers. The pleat - like convolutions of the cerebellum are folia. Cerebellar gray matter is the cerebellar cortex. Flocculonodular nodes are part of the flocculonodular lobe of the cerebellum, not the arbor vitae.

Answer:

C. cerebellar white matter
