Multiple Sclerosis Multiple sclerosis is an autoimmune‚ is a chronic‚ often disabling disease that attacks the central nervous system (CNS)‚ which is made up of the brain‚ spinal cord‚ and optic nerves. Symptoms may be mild‚ such as numbness in the limbs‚ or severe‚ such as paralysis or loss of vision. The progress‚ severity‚ and specific symptoms of MS are unpredictable and vary from one person to another. Today‚ new treatments and advances in research are giving new hope to people affected by

The Study of Neuroscience By definition‚ Neuroscience is the study of the brain and nervous system and is considered a biological science. Neuroscience focuses on neurons‚ a nerve cell‚ of which the brain is made of tens of billions. Every neuron contains a nucleus that contains the DNA of the cell‚ just as most other cell types do. Unlike other cells‚ Neurons have the unique ability of communicating with one another via electrochemicals. Neurons also vary in length‚ some only a millimeter or two

Before discussing treatments‚ it is important to understand the general characteristics and causes of Parkinson’s. Recall that it is a progressive disorder of the central nervous system that affects the motor system and usually initiated by the slight noticeable tremor of a hand. Early stages may consist of face showing little to no expression and arms not swinging at all for motor balance during walking; decreasing ability to perform unconscious movements such as blinking and smiling.

I. Title – The Effect of Volume on Heart Rate II. Problem/Research question – Your heart rate can be affected and changed using a variety of things. One thing that can cause your heart rate to change is the volume of audio. How does the volume of an audio track affect your heart rate? If the volume of an audio track is increased‚ the number of hearts beats per minute will increase as well. III. Variables – ❖ Independent Variable ➢ The volume of the audio track ❖ Dependent

ingredient in all of the cans is water‚ either carbonated or not. All of the cans have taurine‚ which is a non-essential amino acid‚ which supposedly increases reaction time. Another main ingredient in all of the drinks is caffeine‚ which is a Central Nervous System Stimulant‚ and may increase productivity. 2. The psychological role of each of these drinks is supposedly to give you energy‚ but I think it is all a placebo effect. 3. The ingredients that provide energy are Fructose‚ Glucose‚ Glucuronolactone

Interview The professor I decided to interview is my biology teacher Kane-Barnese because I am a biology major and wanted to learn more from a once Concordia student that graduated with a degree in biology. She is a new teacher that seemed a little nervous at first but now she has become a good teacher and I look forward to going to her biology class every Monday‚ Wednesday‚ and Friday from 8:30am to 9:20am. She is also my biology lab teacher‚ that is my favorite class because we get to do hands on
