The part of the cerebrum that controls voluntary movement is located at the back of the head and is known as cerebellum. The function of the cerebellum is to control all voluntary movements of a person. It also controls the movement of the muscles in the body. The cerebellum is considered as one of the three major parts of the brain. Different parts of the brain work in different ways. Each part has their own unique job and it performs the same job on a regular basis. The cerebral cortex is another important part of the braion where all problem solving and thinking is done.
