          BRAIN ATTACK

Everybody most have a brain, the brain is the most important organ also like the hearth, because with the brain we feel, think, and act. We are going to learn how does it works and it´s parts.

When you're taking a big math test, you know that your brain is hard at work. But your brain is doing a lot more than just remembering formulas. Those sweaty palms you get as the test starts? That's your brain at work. The relief you feel when you know an answer's right? That's your brain too. And yes, your brain is even in charge when you take a minute to daydream about the big party coming up on Friday night.

Body Basics: Brain and Nervous System

The brain may simply be the bossiest part of the body: It tells virtually every other part of your body what to do, all the time, whether you're aware of it or not.It not only controls what you think and feel, how you learn and remember, and the way you move your body, but also things you might be less aware of — such as the beating of your heart and whether you feel sleepy or awake.

The Brain & Nervous System in Everyday Life

If you think of the brain as a central computer that controls all the functions of your body, then the nervous system is like a network that relays messages back and forth from it to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part.

During the early years following birth, humans manufacture an estimated 250,000 neurons per minute and then spend the next few years wiring them together. Traditionally, it was assumed that this neural plasticity settles down by adulthood.

          

Central Nervous system 

the central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord. The peripheral nervous system (PNS), is composed of nerves leading to and from the CNS, often through junctions know as ganglia.

The central nervous system is so named because it integrates information it receives from, and coordinates and influences the activity of, all parts of the bodies of bilaterally symmetric animals—that is, all multicellular animals except sponges and radially symmetric animals such as jellyfish, and it contains the majority of the nervous system.[citation needed] Arguably many consider the retina and the optic nerve (2nd cranial nerve), as well as the olfactory nerves (1st) and olfactory epithelium as parts of the CNS, synapsing directly on brain tissue without intermediate ganglia. Following this classification the olfactory epithelium is the only central nervous tissue in direct contact with the environment, which opens up for therapeutic treatments. The CNS is contained within the dorsal cavity, with the brain in the cranial cavity and the spinal cord in the spinal cavity. In vertebrates, the brain is protected by the skull, while the spinal cord is protected by the vertebrae, both enclosed in the meninges.

          

 Brain function 

The brain processes sensory information, controls and coordinates the movement, behavior , feelings and can even prioritize the homeostatic body functions such as heartbeat , blood pressure , fluid balance and body temperature . However, the charge to take the automatic process is the medulla . The brain is responsible for cognition, emotion, memory and learning.

The processing and storage capacity of wa standard human brain surpasses even the best computers today [citation needed]. Some scientists have the belief that a brain that perform a greater number of synapses can develop greater intelligence than one with less neuronal development.

Until not long ago , it was thought that the brain had exclusive operating areas until through imaging it was determined that when a function is performed, the brain acts similarly to a symphony orchestra several areas interacting with each other. Furthermore it was established that when a non- specialized brain area is damaged, other areas can make a partial replacement of their duties.

In conclusion the brain is most important organ in all our body, some people think that the hearth or the lungs, but without all the function of the brain, our hearth can't beat and we can't breathe. With our brain we do every action, we can think, feel, speak, move, and all things that we do, in every moment and the involuntary things we do is thanks to our brain.
