The nervous system is responsible for everything that helps us, think, feel and move. Each part of are nervous system control a particular functions. So that means that damage to a particular areas results in lose of some functions. Ex: If the nervous tissue in your right eye is destroyed, you lose your vision in your right eye.
The brain and spinal cord make up the central nervous system. From there the nerves extend throughout the body to make up the peripheral nervous system. Meaning, MS affects only the central nervous system.
The brain itself consists of two main areas: a pair of hemispheres on top, and the brainstem on the bottom. The hemispheres ( one on each side) are connected together by a bundle of fibers called the corpus callosum. Each hemispheres is divided into four main lobes are used mainly for planning, judgement and movement; the temporal lobes for memory; the parietal lobes for sensing; the occipital lobes for vision.
Far inside the hemispheres lies the limbic system, an area involved in your emotions.
The brainstem carries electrical impulses from the hemispheres down to the nerves in the spinal cord, and from the spinal-cord nerves up to the hemispheres. just behind the brainstem lies the cerebellum, the organ that control our sense of balance and coordination.
