One of the most complex and important mechanisms in the human body is without a doubt the cerebellum, which is the Latin name of the small brain. Considering that the cerebellum is also called ‘small brain’ or ‘little brain’, it is obvious that it is an extremely important part of the brain. The cerebellum has many vital functions, and we would not be able to function properly without it. In fact, we would not be able to function at all, because the cerebellum is highly responsible for the motor control, language, attention and mental imagery. While there are many scientific details that people know about the cerebellum, there are some interesting facts worth knowing as well.
The cerebellum has been considered for a very long time the main responsible for our balance and everything that has to do with the motor function. Nowadays, recent studies have shown that the cerebellum plays an important part in other cognitive functions, as well, like our attention, the way we focus and capture images. Breathing, sleeping, blood pressure and heart rate are also controlled by the cerebellum, because it sends information to the spinal cord and to its neighbouring sections as well. The cerebellum is the second largest section in the brain, and it is located at its bottom. The large mass of the cerebral cortex, which represents about 85% of the brain, lays on top of the cerebellum. Even if the cerebellum is smaller, its importance is undeniable.
Moreover, the cerebellum makes up only 10% of our brains, but it holds up nearly half of the neurons in the entire brain, which is another proof of its importance to the human body. Another interesting fact about the cerebellum is that, when you are driving your car, for example, while the cerebrum will send signals to your hands and arms, ‘telling’ them how to move, the cerebellum is actually the one that will coordinate them for precision. So if you are sitting comfortably, while enjoying reading this article, with your balance intact, it is all due to the cerebellum, the magnificent brain structure that controls how we perceive things through our senses.
