• D. None of the above

Answer 1

The correct option is A Voluntary actions

The arbor vitae is the cerebellar white matter, so called for its branched, tree-like appearance. The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements, such as posture, balance, coordination and speech, resulting in smooth, balanced muscular activity.
