Now you know more about all the cool things you can do your brain. Your brain always takes care of you, so you return the favor! Try either the brain alimentándote well, exercising and getting enough sleep. Protegeles always using a helmet when practicing sports or going by bicycle. Do not drink alcohol or use drugs or smoke snuff - the cells in your brain abhor all these things, because destroy! Take care of your body's head and you will not disappoint - is working harder!
Location of emotions and brain
With all the other things we do, are you surprised that the brain is responsible for your emotions? Maybe get the toy you wanted for your birthday and you're very happy. Or your friend is sick and you feel sad. Or your little brother you have the messy room and are very angry! Have you ever wondered where they come from those feelings? All come from the brain that controls all the emotions you feel.
The brain has a small group of cells on each side called the amygdala. The word "amygdala" comes from the Latin word for "nuts" and that is the aspect that has this area. Scientists believe that the tonsils are responsible for emotions. So when you're sad about a friend who moves, your tonsils are working hard. But not everything that makes the amygdala is bad - also makes you feel excited when you win your soccer game.
It's normal to feel all sorts of emotions, good and bad. Sometimes you can feel a bit sad and ask why. And sometimes you can feel scared, silly or happy. These feelings are part of what makes us human
The hypothalamus
Last but not least, the hypothalamus, which is right in the center of your brain, in the midst of the action. The hypothalamus is like the thermometer of your brain. Know what your body temperature should be (about 98.6 degrees Fahrenheit or 37 degrees Celsius) and transmits messages that tell your body whether to sweat or shiver. Why? Heat and sweat when you have a cold shiver when it is the manner in which your body tries to maintain constant temperature - irrespective of what they're doing or the external temperature. Do you remember the last time you ran and sudaste much? Your hypothalamus was able to realize that your run temperature was rising by so much and sent a message to your skin so that sudara. When you start to sweat, your body began to cool.
The pituitary gland
The pituitary gland is very small - is about the size of a pea! His job is to produce and release hormones in your body. If the clothes of last year I was very young, it is because the pituitary gland has released special hormones that you have made it grow. This gland also plays an important role during puberty. This is the time when the bodies of boys and girls go through major changes as they slowly become men and women - all thanks to hormones released by the pituitary gland. This small gland is involved with many other hormones, such as those that control the amount of sugar and water in the body. And keep your metabolism asset - your metabolism is everything that happens in your body to keep it alive and growing and to give you energy, like breathing, digesting food, and circulating blood
The hippocampus
The hippocampus is an incredibly great, because the use to remember the way to school! The hippocampus is part of the cerebral cortex and is the area of the brain that handles memory. There are different kinds of memory: these are two of the calls short and long term. Try to remember what you have breakfast today - this is an example of the short-term memory. This is information that your brain has just received. Now think of your first day of school or at the birthday party last year. These are examples of events saved on your long-term memory.
Your hippocampus is the great task of transferring information between memories in the short term and long term. It's hard work, but the hippocampus is always there, making sure you remember the little things, like where you left your yo-yo, and also the big things, like vacations where you went camping for two summers.
The brainstem
The brainstem
Another part of the brain that is small but powerful is the brainstem that is located below the cerebral cortex and cerebellum ahead. The brainstem connects the rest of the brain to the spinal cord, which covers your neck and back. The brainstem handles all the functions necessary to ensure that your body is alive, such as breathing, digestion of food and blood circulation.
Part of the role of the brainstem is to control involuntary muscles - those that run automatically, without thinking what. There are involuntary muscles in the heart and stomach, and is the brainstem who tells your heart to pump more blood when you go by bicycle or on your stomach to digest this piece of birthday cake you just eat. (Remember the cortex that controls voluntary muscles. Monitor all the muscles of the body is too big a task for part of the brain!). The brainstem also classifies the millions of messages that the brain and the rest of the body are sent. Uf! It's enough work to be the secretary of the brain!
The cerebellum
The cerebellum
The next part is the cerebellum. The cerebellum is in the back of the brain, below the crust. It is much smaller than the cerebral cortex, only 1 / 8 of its size. But do not let the small size of the cerebellum fool you - is working hard between racks, controlling the balance, movement and coordination (how your muscles work together). Thanks to the cerebellum can stop you erect, maintain balance and move from side to side. Think of a surfer uploaded to your table on the waves. What is it that more needs to maintain balance? The best table? The suit cooler? None of this - you need your cerebellum!
nervous system
The nervous system controls everything you do, for example, breathing, walking, what you think and what you feel. This system consists of the brain, spinal cord and all the nerves of the body. The brain is the control center and the spinal cord is the main highway that connects with him. Nerves transmit messages to the body and from the brain to interpret and act accordingly.
nerve tissue
Nerve tissue
Nerve tissue is composed of interconnected neurons. Between the Blutkapillaren glial cells connect with other neurons and glial cells. Through these nerve cells is associated nerve tissue from other tissue types identifiable. Nerve tissue is mainly in the brain, spinal cord and peripheral nerves to find, but also at the gut (→ Enteric Nervous System) and in the retina are net related nerve cells.
In the living organism has the nerve tissue the color pink to white. In the gray matter outweigh nerve cells. The white matter consists of cable railways, the myelinhaltigen nerve fibers. In the white matter, networking is low.
Nerve tissue leads selectively excitement of receptors on the success of organs. The gray matter processed, the white heads.

Building
Schedule a nerve cell . Basic building block of the nervous system is the nerve tissue. It consists of interconnected nerve cells (neurons), whose cell body as Somata or Perikarya and their survival rates than nerve fibers (axons and dendrites) respectively.
At higher organisms, the nerve tissue from a network of neurons and glial cells many places to dock. The latter support the activity of nerve cells, without directly to the transmission of stimuli to be involved.
Cephalopods and vertebrates nervous systems
Cephalopods and vertebrates
Especially highly centralized systems are the nerves of cephalopods and vertebrates. They are a great many functions of the nervous system and muscles of the centrally controlled. It therefore speaks of a central nervous system. This consists of the brain and the spinal cord.
The outside of the central nervous system underlying neural structures to be counted peripheral nervous system. The peripheral nervous system is divided into the somatic nervous system and the vegetative nervous system (including visceral or autonomous nervous system, consisting of sympathetic, and enteric nervous system Parasympathikus) broken. The vegetative nervous system is primarily concerned with controlling the activities of the outside of consciousness expiring body functions.
Arthropod nervous system
Arthropod
Schematic construction of a knitting head of nervous system
In the arthropod is already in the training of higher processing centers in the form of several nerve knots (ganglia). These ganglia are two nerves like knitting heads together, so we here of a knitting nervous talking head. For most of these animals is particularly great Oberschlundganglion trained. It already assumes the functions of a "brain", especially the processing of sensory stimuli. The ganglia of body segments often control the movements of the leg and wing muscles largely autonomous. The knitting head nerve systems (with the exception of the upper pharyngeal Gang Lions) below the digestive system. Therefore, one speaks also of abdominal Mark.
Evolution
Evolution
In the course of evolution and with the higher development of individual departments of the animal kingdom is a clear trend towards concentration and associated specialization of parts of the nervous system noted. While in primitive animals, yet some individual neurons fall special functions (eg pacemaker neurons, the clock for elementary body movements of worms pretend), to perform highly complex nervous systems of up to several billions of interconnected neurons in specific tasks.
In nervous systems with Zentralganglien the conduction of neurons in Afferenzen (from the sensors to the brain) and Efferenzen (from effectors to the brain, muscles, for example) are divided.

Overview of the human nervous system
The term nervous system (Systema nervosum lat) is the totality of nerve cells in an organism and describes how they arranged and connected. It is an organ system of higher animals, which has the task to provide information on the environment and the organism record, process and reactions of the organism action to optimal to react to changes. The nervous realized one of the basic properties of life, the irritability (irritability).
