Answer D. Cerebellum
- The cerebellum, which stands for “little brain”, is a structure of the central nervous system. It has an important role in motor control, with cerebellar dysfunction often presenting with motor signs.
- The cerebellum is located at the back of the brain, immediately inferior to the occipital and temporallobes,and within the posterior cranial fossa.
- It is separated from these lobes by the tentorium cerebelli, a tough layer of dura mater.
- It lies at the same level of and posterior to the pons, from which it is separated by the fourth ventricle.
