An amazing system

Well today I talk to you about which's my favourite system of our human body. I love the central nervous system because absolutely everything we do, it's a order of our brain, the brain is the vital organ most important, it's charge of all biological processes that occur in the organism, the brain is part of the central nervous system (CNS), this is formed by the encephalon (brain and the spinal bulb)  and the spinal cord. the CNS is responsible for receiving and processing the sensations (stimulus) catched by the different senses and transmitting the response orders in a precise manner to the different effectors organs.

The brain and spinal cord are both enclosed in the meninges. Within the CNS, the interneuronal space is filled with a large amount of supporting non-nervous cells called neuroglial cells. 
This system is localized from the head to the lower back, lumbar zone, it’s protected by the skull, the vertebral column and cerebrospinal fluid. The size of the CNS occupies 1/2 of the human body.
The cells of this system it’s named “neurons” these are responsible for making the synapse and this way our organism can realized any activity.

There are many CNS diseases and conditions, including infections such as encephalitis and poliomyelitis, early-onset neurological disorders including ADHD and autism, late-onset neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and essential tremor, autoimmune and inflammatory diseases such as multiple sclerosis and acute disseminated encephalomyelitis, genetic disorders such as Krabbe's disease and Huntington's disease, as well as amyotrophic lateral sclerosis and adrenoleukodystrophy. Lastly, cancers of the central nervous system can cause severe illness and, when malignant can include alterations in motor control, hearing loss, headaches and changes in cognitive ability and autonomic functioning.
