1. THE NERVOUS SYSTEM Rona Antiquiera, Jose Lopez, Umer Abid, Dulce Hernandez, Ai He

2. WHAT DOES IT DO?  The Nervous System collects information pertaining to the body’s external conditions.  Taking this information, the nervous system analyzes it in relation to the body’s needs to provide suitable responses for survival  Made up of 3 different systems…

3. CENTRAL NERVOUS SYSTEM  The brain and spinal chord Transmits information back and forth Responsible for subconscious functions (Like heartbeat and digestive systems…)

4. ENDOCRINE SYSTEM  Glands The pituitary gland, the pancreas, reproductive glands, the thyroid gland, the parathyroid gland, and the adrenal glands Controls rate of growth, body temperature, hunger…

5. PERIPHERAL NERVOUS SYSTEM  Nerve cells (or neurons) They are “wired” together to transmit information in the form of electrical impulses Have the ability to repair themselves to an extent (cannot be repaired if damaged by injury or disease)

8.  Parkinson's disease is a disorder of certain nerve cells in the brain that normally produce a chemical called dopamine, which helps the brain direct and control movement. Parkinson's Disease

9.  shaking (tremor)  stiff muscles (rigidity)  slow movement (bradykinesia)  have a stooped posture  blank stare or fixed facial expression  speech problems  problems with balance or walking  may also have confusion and memory loss The classic symptoms of Parkinson's disease

10.  There is no cure for Alzheimer's disease. But much can be done, including medicines and behavioral modifications, to maintain the person's quality of life and to help the person stay active. Many people with Alzheimer's disease can be cared for at home. Alzheimer's disease causes

11.  Alzheimer's disease is a progressive condition that damages areas of the brain involved in memory, intelligence, judgment, language, and behavior. Alzheimer's Disease

12.  There is no cure for Alzheimer's disease. But much can be done, including medicines and behavioral modifications, to maintain the person's quality of life and to help the person stay active. Many people with Alzheimer's disease can be cared for at home. Alzheimer's disease causes

13.  is a common and diverse set of chronic neurological disorders characterized by seizures. Some definitions of epilepsy require that seizures be recurrent and unprovoked, but others require only a single seizure combined with brain alterations which increase the chance of future seizures. Epilepsy Disease

14.  During the neonatal period and early infancy  hypoxic ischemic encephalopathy, CNS infections, trauma, congenital CNS abnormalities, and metabolic disorders.  During late infancy and early childhood  These may be caused by many different things, some thought to be things such as CNS infections and trauma.  During childhood, well-defined epilepsy syndromes are generally seen.  During adolescence and adulthood  stress, trauma, CNS infections, brain tumors, illicit drug use and alcohol withdrawal. Different Causes of epilepsy

15. Exercise is an important part of caring for the nervous system. Be sure you are getting at least 15 to 30 minutes of aerobic activity at least three times a week. This will help your nervous system control the body. Regular exercise can cause beneficial adaptations to your central nervous system. For example, connections between nerve endings and skeletal muscle become more efficient, making it easier for your body to perform a given activity. HOW TO CARE FOR This SYSTEM

16. The brain plays a major roll in the nervous system. All the other parts of the nervous system report back to the brain. One of the easiest ways to do this is to play small brain games every day. Water is a necessary part of nervous system functions. After all, about 70% of the body is water! Drink plenty of water every day. At least 8 glasses is the minimum you should be drinking, although some people say that the body needs more.

17. Processed and pre-prepared foods are some of the worst for the body and nervous system. A lack of nutrition can make someone more susceptible to nervous breakdowns and other health risks associated with the nervous system. Stay away from refined sugars and processed foods. Switch to sea salt rather than regular table salt. Coffee, tobacco, and alcoholic drinks are not good for the nervous system.

18. Your brain, spinal cord, and peripheral nerves are coated with a layer of fat, called myelin, which provides insulation to your nervous system. When myelin is not properly maintained or is eroded by autoimmune illness, you are bound to experience any number of symptoms of nerve dysfunction. Ensure adequate intake of healthy fats, and ensure adequate vitamin D and vitamin B12 status. All are essential to maintaining optimal myelin and nervous system health.
