The Nervous System The nervous system is one of the most important systems in the human body because it sends out messages from the brain into the body parts and coordinates the body activities. This allows the body to have and be in control. The two major systems in the nervous system are the peripheral system and the central system. The autonomic nervous system is the last nervous system which controls internal body functions such as temperature regulation, blood pressure, and all other functions dealing with blood, digestive system, and excretory system. The central and the peripheral both have different functioning parts and they also control the different processes throughout the body. The central system is connected from the brain to …show more content…
The central system is the part of the body that makes decisions and sends signals throughout the body to react to any situation that is occurring. The peripheral system specifies where the signals sent from the central nervous system go. They work together to maintain the body’s voluntary and involuntary movements. The peripheral system contains the somatic nerves and the autonomic nerves, which leads to sympathetic nervous system and the parasympathetic nervous system, (Mandal, 2010). There are hundreds of billions of neurons in the human brain, while there are millions of nerve cells throughout the entire human body. The neurons control all of your five senses: touch, smell, taste, sight and hearing. There are thin fibers in the brain, or axons, which receive signals sent from neurons (Zimmerman, 2016). If there happen to be any faults in the nervous system, neurological diseases such as …show more content…
The cerebellum, which is affected by epilepsy, is connected to the spinal cord, the spontaneous electrical currents in the brain causes uncontrollable spasms in the externalities of the body. Some of the symptoms that take place before seizure attacks are feeling light headed, uncontrollable body movements and may have blurred vision. This can lead to a seizure which is identified by uncontrollable shaking, eyes rolling to the back of the head, and the mouth may form white foam. Family history plays an essential role in the probability of someone being diagnosed with epilepsy. As each day passes stress builds up, this can be a lead source that triggers seizers. If any immediate family member has epilepsy it would be wise to be cautious in your day-to-day life so that stress won’t build up and cause you to have a seizure. Traumatic events such as a car accident, where you may hit your head and cause brain damage, are also causes of epilepsy or seizures. Once you have a seizure doctors will scan your brain to check and see what is occurring in your brain. MRI scans, or magnetic resonance imaging, are ways a doctor may check for an optimal image of your brain to check for any problems that may cause seizures. In this case, dead brain cells and or damaged brain
