The brain is the center of the nervous system in all vertebrate and most invertebrate animals.[1] Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste, and smell. The cerebrum is the biggest portion of the brain. This part, the cerebrum deciphers troubles and composes your needs. It’s kind of like a Gene in a bottle that grants wishes! This is where all the thinking takes place. The language you speak and the expression of emotions come from your cerebrum. Especially from your cerebral cortex that is on the outside of your cerebrum. This is where all the thinking takes place. The language you speak and the expression of emotions come from your cerebrum. Especially from your cerebral cortex that is on the outside of your cerebrum. Your body movements are synchronized and harmonized by the cerebellum. It takes a cerebellum to hit a home run. Your cerebrum will tell your hands and arms to move, but your cerebellum will coordinate for precision in order for you to drive it out of the yard. Yea! Here’s a fun fact: The cerebellum makes up only 10% of the brain, but holds up to half the neurons in the entire brain In vertebrate anatomy the brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord. The brain stem provides the main motor and sensory innervations to the face and neck via the cranial nerves. Though small, this is an extremely important part of the brain as the nerve connections of the motor and sensory systems from the main part of the brain to the rest of the body pass through the brain stem. This includes the corticospinal tract (motor), the posterior column-medial lemniscuses pathway (fine touch, vibration sensation and proprioception) and the spinothalamic tract (pain, temperature, itch and crude touch). A longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. The sides resemble each other and each hemisphere's structure is generally mirrored by the other side. Yet despite the strong similarities, the functions of each cortical hemisphere are different Broad generalizations are often made in popular psychology about certain functions (eg. logic, creativity) being lateralized, that is, located in the right or left side of the brain. These ideas need to be treated carefully because the popular lateralizations are often distributed across both sides. A well-balanced brain keeps away several ailments such as stress, anxiety, loss of memory, dementia, paralysis etc. But how to keep the brain healthy? Provide it with all the necessary ingredients that it needs – the minerals, the vitamins, and oxygen as well as water too.
