The human brain has more than 100 billion neurons, all of which have a specific function and task. To understand the brain we must examine its parts and functions. This includes the cerebrum, cerebellum, and brainstem and the functions within them. To fully understand the brain, look at its main parts and delve deeper into those. There are 3 main parts of the brain: cerebrum, cerebellum, and brainstem. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

The cerebellum is what allows us to be good at sports and athletics, without it I doubt we could do anything even remotely resembling an athlete if we didn't have it. It is what coordinates voluntary muscle movement, maintains posture and balance. Even though it appears to be only a small part of the brain, we wouldn't live the same lives if we didn't have it. The brain stem, which is the body's regulator for all involuntary movements and a relay center for the brain and body. It is composed of three parts: midbrain, pons and medulla oblongata. The brain is the largest of the three main parts and makes up about 85% of the brain. It is composed of a left and right hemisphere. Both hemispheres control opposite sides of your body. The right controls the left and the left controls the right. In all hemispheres not all functions are shared. The right side of your brain controls more imagination and creativity, things more music and art oriented. While the left side is more analytical, it deals with logic, reasoning with the same things used in mathematics. But the brain controls the higher functions of the brain. Touch, vision, hearing, speech, reasoning, learning, and fine motor controls such as the ability to move your fingertips are all things the brain is responsible for. Without your brain you wouldn't be yourself. From the brain we can further break it down into individual lobes that have certain functions that differ from each other. The first group of four lobes are the frontal lobes which reside at the front of the brain and continue up to about the first half of the brain. From the frontal lobe it is broken down into certain sections of the brain. The motor cortex and precentral gyrus deal with motor skills and voluntary movement. Next to the motor cortex is a section of the brain called the premotor cortex; It gives the body the ability to move the head and eyes but also gives it an orienting presence. It also has another part called the prefrontal cortex that plays a role in what makes you you. The prefrontal cortex deals a lot with memory, intelligence, concentration, temperament and personality. After the frontal lobes are the occipital lobes which do not reach the brainstem but the upper section from the second quarter to the third quarter of the brain. The occipital lobe gives the brain the ability to process the visual information it receives. It influences how humans perceive colors and shapes. The right side interprets the left and vice versa.

It is located above the side of the ear, on the other side of the brain. The occipital lobes can be divided into two different parts: ventral, inferior, and lateral, lateral. On the right side of these two lobes is the part of the brain that helps humans recognize objects and people's faces..
