I am finally back (hopefully!), the weather caused a crash with me and my MS and I've found it fairly hard to recoup the desireto quite simply blog for a very long time I know!
Moving on, our nervous system. Surprisingly many people have very little idea about what it is and what it does in our bodies with some people trying to comfort when I may tell them I have nerve condition by saying it'll be fine come sit next to me if you wish (thinking I meant I am nervous!)
Quite simply our nervous system is involved with pretty much everything in our bodies. For the functions of the body, for example our organs or muscles. The nervous system is responsible for sending action potentials ( simply put, messages)
The nervous system of the human being is responsible for sending, receiving, and processing nerve impulses throughout the body. All the organs and muscles inside your body rely upon these nerve impulses to function. It could be considered as the master control unit inside your body. Sense organs provide the nervous system with information about the environment by means of such senses as sight, hearing, smell, taste, tough, pressure, and pain. Nerves are connected throughout the whole body to the brain. They carry the information throughout the body in the form of electro-chemical signals called impulses. These impulses travel from the brain and spinal cord to the nerves located throughout the body. For example, if we touch something, impulses travel through the nerve network to the brain at a rate of 350 feet per second. It is largely made up of specialized cells called neurons. Each of these neuron has a cell body, which contains the nucleus and organelles. It takes the corporation of three system to carry out the mission of the nervous system . They are the central, the peripheral, and the autonomic nervous systems.
The central nervous system has the responsibility for issuing nerve impulses and analysing sensory data, and includes the brain and spinal cord.
The peripheral nervous system is responsible for carrying these nerve impulses to and from the body? many structures, including many nerve pathways which branch off the brain and the spinal cord.
The autonomic nervous system is composed of the sympathetic and parasympathetic systems ( the sympathetic in charge of preparing the body for intense physical activity and the parasympathetic doing the opposite, relaxing muscles) and is responsible for regulating and coordinating the functions of vital structures in the body which a lot of the time are things we don't pay attention to (thankfully!) like control of breathing and heart rate.
I know it seems like a science book, but hopefully it'll put things into perspective for the coming posts, hopefully I don't bail out again, wish me luck!
