Human Body and Mind

Body and mind

Information in the form of nerve impulses traveling to and from the brain along the spinal cord. This allows your brain to control and regulate unconscious, such as digestion and breathing bodily processes and to coordinate voluntary movements over your body. It is also the site of his conscience, which allows you to think, learn and create.

Your brain is made up of many parts, each of which has a specific function. It can be divided into four areas: the brain, diencephalon, brain stem and cerebellum.

Cerebrum

The brain is the largest part of your brain. It is on top of the rest of his brain, rather like a mushroom cap covering its stem. Has a strongly folded gray surface, the pattern is different from one person to the next. Some of the grooves on its surface mark different functional regions.

The front section of your brain, the frontal lobe is involved in speech, thought, emotions and skilled movements. Behind this is the parietal lobe which perceives and interprets sensations like touch, temperature and pain. Behind it, in the back part of your brain center, is a region called the occipital lobe, which detects and interprets visual images. Any of the parts of the brain are the temporal lobes are involved in hearing and memory storage.

The brain is split down the middle into two halves called hemispheres communicate with each other.

Cerebellum

Your cerebellum is the second largest part of your brain. It is located below the back of his brain and is shown in brown in the diagram above. It is involved in coordinating muscles to allow movement and balance control and precise posture.

Diencephalon

Your brain is below half of your brain and the upper part of his brain stem. It contains two important structures called the thalamus and hypothalamus. Your thalamus acts as a relay station for incoming sensory nerve impulses, sending them to the appropriate regions of the brain for processing. It is responsible for allowing your brain knows what's happening outside your body.

The hypothalamus plays a vital role in maintaining the conditions inside your body constant. This is done by regulating body temperature, thirst and hunger, among other things. And by controlling the release of hormones from the pituitary gland near.

Brain stem

His brain stem is responsible for regulating many mechanisms to support life, such as heart rate, blood pressure, digestion and breathing. It also regulates when you sleep and wake up.

Brain protection

Your brain is arguably the most important organ, but is made of soft and delicate tissue it would be hurt by the slightest pressure. As a result, it is well protected:

Three strong membranes called meninges surrounding the brain

The space between the brain and the meninges is filled with a clear fluid that cushions the brain, provides energy and protects against infection
