...The terminal swing phase is considered the most hazardous as the hamstring muscle-tendon units are at their longest length of the gait cycle and are most heavily activated (Opar et al., 2012, pg. 212). At this point the eccentric contraction of the hamstring muscles elicit a high force to decelerate knee extension and hip flexion. The results of previous studies demonstrate that muscle strain in eccentric contraction is the primary cause of the muscle strain injury affected by muscle strength and contraction velocity (Liu, et al., 2012, pg....

...Proteins Mary Ann Edmonds Lincoln College Online Proteins Since studying about nutrition and weight loss and working on each assignment every week and learning new ideas and ways to eat healthier has brought a new perspective to also cook healthy foods for my son as we try to stay away from fast foods. Upon coming to the final learning assessment I already knew which one I was going to do my research paper on and I choose to do proteins because I am learning about them after the weight loss surgery that I had done about three months ago and it has some interesting facts that I did not even know about. So after studying about nutrition we all should know that proteins are molecule cells that are always hidden throughout our body that serve as important functions will also help to defend anybody to help maintain and protect you against any and all invading organisms and to help in maintaining the PH balance that lies within the stomach. Proteins are also known to be made up from amino acids that form a three dimensional shape so that we know the functions of proteins that are hidden throughout our body will also vary by structure. So we will go ahead and list and describe the six different kinds of proteins and their functions on what they do as well. Enzymes is a type of protein that is also known to be called a catalyst and this is so that it speeds up the chemical that lies within the body. I will go ahead and give a good example for this and that would be because...

Min Hsuan Wang (U#23090118) Introduction Caenorhabditis elegans is a very important study model that is used for many genetic study because of its features like transparent, easy to handle, short life cycle etc. The feeding behavior is very important in the feeding method of the RNAi silencing experiment that use C. elegans to study genetic. The feeding of bacteria could influence the efficiency of the RNAi silencing. The feeding behavior of C. elegans involves uptake of bacteria, pharyngeal pumping, and isthmus peristalsis.To soak the bacteria inside the C. elegans require pharyngeal pumping to initiate the muscle contraction so that the bacteria can be ingested inside, then followed by the contraction of isthmus...

II. INTRODUCTION Tetanus comes from the Greek word “teiteim” which means to stretch. It is also called lockjaw. It is a serious infectious disease of the nervous system in which toxin causes severe muscle spasm. It is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. It is caused by a bacterium Clostridium tetani. Infection generally occurs through wound contamination and often involves a cut or deep punctured wound. Tetanus is often associated with rust, but this concept is somewhat misleading. The C.Tetani is an Anaerobic bacteria which survives in an environment that lacks oxygen, thus with or without rust a person may have a tetanus once C. Tetani...

...| Research Paper Part 1 – Introduction & Body Paragraphs | EN 1320 | | Anthony Brown | Week 8 | | Myasthenia Gravis (pronounced My-as-theen-a Grav-us) derived from the Greek and Latin words and it means “grave muscle weakness.” Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body ("National institute of," 2012). The prevalence of MG in the United States is estimated to be about 20/100,000 people ("What is myasthenia," 2010). MG is a rare but very serious disease and many people who have been diagnosed do not recognize the symptoms. If detected early, MG can be treated successfully with, if any, very little side effects in the future. Once diagnosed with MG, that person must go through a drastic life change; Enduring rigorous treatments depending on how aggressive the disease has become, possibly undergoing a life threatening surgery, and living with myasthenia gravis for the duration of their life. “Muscle weakness caused by MG progresses as the effected muscle is used repeatedly. Since symptoms typically improve with rest, but your muscle weakness may come and go” (Staff, 2010). The first signs and symptoms of MG are ptosis and diplopia. “Ptosis is a drooping of the upper eyelid. The lid may droop only slightly, or it may cover the pupil entirely” (What is ptosis?, N.d.). “Diplopia (double vision) is a common subjective complaint, or diplopia may...

...Nadira Farha Extra Credit Paper Dr.Adviye Tolunay 11/25/14 “Sleep” Do you ever wonder why you don’t dream when you sleep? The truth is, if you are getting proper amounts of sleep in proper time periods, and not taking medications or using alcohol or illegal substances, you are dreaming. You just don’t remember them unless they wake you. Sleep has been determined like a state optimizes the consolidation of newly acquired information in memory. It depends on the specific conditions of learning and the timing of sleep. Sleep is divided into two states: rapid eye movement (REM) sleep and non-rapid eye movement (NREM), which involves slow wave sleep (SWS, stage 3 and 4) and the others is lighter sleep which occurs on stage 1 and 2. First, stage 1 When we are preparing to drift off, we go though Alpha and Theta, and have periods of dreaminess, almost like daydreaming, except we are beginning to fall asleep. These are interesting states, in that we experience them throughout the day and some people may have more of these waves than others. Those who practice meditation, or deep prayerfulness, often kind of “hang out” in Alpha. It’s a restful place. During this stage, it’s not unusual to experience strange and extremely vivid sensations or a feeling of falling followed by sudden muscle contractions. These are known as hypnogogic hallucinations. You may even feel like you are hearing someone call your...

...Electric Pants Research Paper Hannah Bradley Finger Lakes Health College of Nursing Electric Pants Research Paper Bedsores are a common injury among the elderly and individuals who have disabilities that make them mobility challenged. Bedsores also known as, “pressure ulcers” are most commonly found along the buttocks, heels, shoulder blades or the back of the head. This occurs when blood flow is cut off to the surrounding cells, causing the muscles to be starved of proper nutrients and oxygen. This forces the tissues to break down. Pressure ulcers are common among individuals who are immobilized and those who sit in the same position for hours at a time. Bedsores can be devastating but with new electronic advances they can be prevented. Traditional practices utilize repositioning of patients every couple hours in order to eliminate bedsores. Now there is an easier way. “Scientists have a developed underwear with built-in electrodes that deliver small electric shocks to combat bed sores in patients who are in a coma or who have injuries that have immobilized them.” (Jha, 2012). These electrodes mimic the effect of moving around and send fresh blood back into the area with every contraction....

...our daily lives, our muscles become binded, underactive, and dysfunctional. Many of us never pay any attention to this occurrence until pain elicits a response urging us to seek medical attention. Of course, many people will turn to traditional medicine for a solution, often receiving medication to cover the pain caused; never correcting the root cause of the pain. As time moves on surgery may be suggested by the traditional practitioner and that solution only affords a few more years before the same symptoms will return or even less time to create a new problem in a surrounding tissue, then the process comes full circle. A reason for the binded, under active, and dysfunctional muscles is the accumulation of scar tissue. By definition scar tissue, or cicatricial tissue, is the dense fibrous tissue forming a matrix, derived directly from granulation tissue. For the purpose of this paper I will use the term scar tissue throughout its length. Scar tissue binds up and ties down tissues that need to move freely. This dense, fibrous tissue affects us all and is an underlying factor in many injuries. As scar tissue builds up, muscles become shorter and weaker, tension on tendons causes tendinosis, nerves can become trapped, and altered movement patterns result causing discomfort often pain. “All these problems can cause reduced range of motion, loss of strength as well as tingling, numbness, and weakness” [1]. Scar tissue forms two different ways: first, if a muscle, tendon, or ligament...

...Anatomy and Physiology 2, SCI 136 Research project # 40904000 Muscular Dystrophy Definition Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement. The word dystrophy is derived from the Greek dys, which means "difficult" or "faulty," and troph, or "nourish." These disorders vary in age of onset, severity, and pattern of affected muscles. All forms of MD grow worse as muscles progressively degenerate and weaken. Many patients eventually lose the ability to walk (“National Institute,” 2011). Some types of MD also affect the heart, gastrointestinal system, endocrine glands, spine, eyes, brain, and other organs. Respiratory and cardiac diseases may occur, and some patients may develop a swallowing disorder. MD is not contagious and cannot be brought on by injury or activity (“National Institute,” 2011). Method(s) of diagnosis Muscular dystrophies are diagnosed through both the patient’s medical history and a complete family history to determine if the muscle disease is secondary to a disease affecting other tissues or organs or is an inherited condition. It is also important to rule out any muscle weakness resulting from prior surgery, exposure to toxins, current medications that may affect the patient's functional status, and any acquired muscle diseases. Thorough clinical and neurological exams can rule out disorders of the central and/or...

...Tay-Sachs Disease Tay-Sachs Disease is a neurological disorder that is passed on from parent to child in the same way that other genetic traits are passed on. The first section of this paper, on pathophysiology, will go into this subject further. It will explain not only how the trait for this disease is passed from generation to generation, but also the specific mutations that cause it. This section will explore the trait that is expressed when the gene is turned on, how it effects cell metabolism, and in turn, the disorder that is caused in the body as a result. The second section will describe the clinical manifestation of the disease. It will cover what is typical in a patient with the disease, initial and continuing symptomology, and unfortunately, the cause of death in most people who have the disease. Lastly, the final section will reveal the medical management of the disease. Tay-Sachs has caused so much suffering, but with the advances made in genetic technology, and a little luck, the current generation of researchers are hoping to change that (Wise, 2012). Pathophysiology Tay-Sachs disease results from a number of different mutations on the fifteenth chromosome. When the gene functions correctly, it results in an enzyme called hexosaminodase. This enzyme breaks down molecules in the body called gangliosides. Without the proper enzyme to break these molecules down, they build up in what are called ganglion cells. These cells then swell keeping the neurons fro functioning...

...calisthenics or light running (White, 2008). In turn, this increases extensibility and flexibility of muscles and tissues. Similarly, the stretching routine also serves to increase the extensibility and flexibility of muscles and tissues. This paper will give the rational for using dynamic stretching, its benefits and the specific movements that one can use during the stretching process. Dynamic stretching is among the preferred stretching techniques used by a majority coaches. It involves the controlled swinging of both arms and legs without stretching out of one’s range of motion. In this case, the stretch is produced by both active muscular contractions and momentum (Reilly, 2007). During dynamic stretching, one uses certain movements depending on their sport in preparation for body movement. This type of stretching tends to be confused with ballistic stretching. This is because if one stretches beyond their static ability, it is no longer dynamic stretching but rather ballistic stretching. This routine of dynamic stretching should begin from low intensity and gradually progress to movements of higher intensity (White, 2008). This is mainly because dynamic stretching calls for both coordination and balance. This form of preparticipation routine serves as an aerobic exercise, which elevates core temperature of an individual. Moreover, it also allows for muscle stretching and preparation for motor skills required in the specific sport. The latter is a crucial...
