<h3>What is the cerebellum? </h3>
The cerebellum is a prominent part of the hindbrain and is located just above the brainstem. The cerebellum controls all the voluntary movements of the body and is also responsible for maintaining balance and posture.
The cerebellum is said to make up for 10% of the brain's volume but has more than 50% of the brain's total neurons.
The cerebellum is made up of two parts; a cerebral cortex, a layer made of folded tissue which contains most of the neurons and cerebral nuclei, an inner part which contains the neurons responsible for communication.
Therefore, the hindbrain develops into the pons, medulla oblongata and cerebellum.
