Metabolic Muscular And Nervous Systems - 1,731 words
The immediate source of energy for muscular contraction is the high-energy phosphate compound called adenosine triphosphate (ATP). Although ATP is not the only energy-carrying molecule in the cell, it is the most important one, and without sufficient amounts of ATP most cells die quickly. The three main parts of an ATP molecule are: an adenine portion, a ribose portion, and three phosphates linked together. The formation of ATP occurs by combining adenosine diphosphate (ADP) and inorganic phosphate (Pi). This formation requires a large amount of energy to and it is called a high-energy bond. In order for a muscle to contract, the enzyme ATPase breaks the ATP bond and releases energy which is ...

... ws the cross-bridge to detach and re-attach to another active site on an actin molecule. This contraction cycle is repeated as long as free calcium is available to bind the troponin and ATP is available to provide the energy. The signal to stop contraction is the absence of the nerve impulse at the neuromuscular junction. When this occurs, an energy requiring calcium pump located within the sarcoplasmic reticulum begins to move the calcium back into the sarcoplasmic reticulum. This removal of calcium from troponin causes tropomyosin to move back to cover the binding sites on the actin molecule and cross-bridge interaction ceases. It is possible for skeletal muscle to exert force without ...

Current Research On Duchennes Muscular Dystrophy - 571 words
Duchenne's muscular dystrophy is the result of a defective gene on the X chromosome. This gene is responsible for production of the muscle protein dystrophin. Dystrophin is an integral part of the dystrophin-glycoprotein complex which bears the brunt of the force generated during muscular contraction. When dystrophin is not produced, the dystrophin-glycoprotein complex (DCG) is not present. Absence of the DCG leads to tears in the muscle membrane because the muscle membrane bears the force of muscular contraction alone. Tears in the muscle membrane allow substances to leak in and out of the muscle fibers at random. This uncontrolled "biochemical traffic" leads to eventual death of the muscle ...

Muscular Dystrophy - 734 words
Muscular Dystrophy Scientists have been struggling with the cause, treatment of, and cure for Muscular dystrophy since its discovery in 1886, by Dr. Guillaume Duchenne. Muscular dystrophy is a hereditary disease, affecting thousands of people every year, two-thirds being children between the age of birth through adolescents. However, Muscular dystrophy can occur with no family history of the disease. Muscular dystrophy is a degenerating disease, in which the skeletal muscles degenerate, lose their strength, and cause increasing disability and deformity. Muscles attached to the bones through tendons are responsible for movement in the human body, however, in muscular dystrophy the muscles bec ...

Greek Art - 982 words
Ancient Greece 950 BCE was a culture that took great pride in perfection, excellence and overall greatness. The people werent what todays society would consider modern, but of their time they were. The Greeks essentially molded the creative world with their intelligence in art, architecture, and astronomy for many cultures to come. The Romans who basically claimed the Greeks developments as their own destroyed many of their ideas and art forms. Even though so much of the Greeks culture has been destroyed, much of it still remains within society today. So many aspects of modern day life have been in some way, influenced by the Greeks. The Greeks were a culture that strived for perfection, and ...

Michelengelo - 1,867 words
The Italian Michelangelo Buonarotti, almost certainly the most famous artist produced by Western civilization and arguably the greatest, is universally viewed as the supreme Renaissance artist (see Renaissance art and architecture). He created monumental works of painting, sculpture, and architecture and left an additional legacy of numerous letters and poems. Through this vast and multifaceted body of artistic achievement, Michelangelo made an indelible imprint on the Western imagination. A member of an old and distinguished Florentine family, Michelangelo was born near Arezzo, Italy, on Mar. 6, 1475, and he died on Feb. 18, 1564, in Rome--a record of longevity that was as unusual as his pr ...

One Flew Over The Cuckoos Nest - 1,638 words
The imagination is the readers most important tool on the path to enjoying a good book. One can only hinder their enjoyment of the story by disregarding the vivid images created by the mind. Nothing can compare to a landscape so exquisite that it would make a cinematographer jealous, or a prison so cold that you can see the inmates hot breath. However, some authors offer help for those who are creatively impaired. In One Flew Over the Cuckoos Nest, the author, Ken Kesey builds such an effective tone, that the shifts in the attitudes of the characters can be detected. In the first half of the novel, Kesey uses a wonderful device to show oppression that makes the reader feel as if they themsel ...

Triumph Or Tragedy - 1,646 words
Never, never, never give up, was coined by Sir Winston Churchill. This quote holds more meaning than could ever be put into words. Everyday we are faced with obstacles that occur in our lives. How we manage these everyday occurrences make us not only who we are, but also who we hope to become. Nineteen hundred eight six was an exceptional year filled with triumph and tragedy. May I never forget lessons learned and innocence lost. Tragic events do not preclude tragic outcomes. Leaving home was probably the hardest thing I ever had to do at the age of seventeen. For seventeen years I lived in the small ranch style house. I always dreamed of leaving, but never thought the time would come. Final ...

In the past three decades, steroids has been becoming a serious problem more than ever in the athletic field. Steroids are anabolic drug "to build" growth hormones that include the androgens (male sex hormones) principally testosterone and estrogen and progestogens (female sex hormones). Steroids were first developed for medical purposes. They're used in controlling inflammation, strengthening weakened hearts, preventing conception, and alleviating symptoms of arthritis and asthma. Unfortunately research has shown that steroids have been abused in almost every kind of sport. Although steroids contribute to a muscular body, usage should remain illegal because they physically deteriorate and m ...

Save The Rainforests - 1,585 words
The destruction of the rainforests is one of the most crucial environmental issues of our time. It is also one of the most misunderstood and neglected. There has been so much propaganda and publicity attached to this crisis that Save the Rainforests is becoming almost as clich as Save the Whales. Why dont we take this problem more seriously? Is it because we, as Americans, simply dont understand the devastating, long-terms consequences that continued deforestation of the rainforests would have? Is it because our own government is involved in the deforestation, either directly or by financing its development? Or is it because we live in a society of excessive consumption, oblivious to the pro ...

Fundamentals Of Fitness - 787 words
When we first took this class I thought I knew all I needed to know about physical education. We learned that fitness is the ability to carry out daily activities with vigor and alertness with out fatigue. When I learned this I thought everyone is fit. I started to realize that older people have difficulty going up and down stairs and other activities that should be easy. As they got older they did not keep fit and started to become unhealthy. If you are physically fit then you will stay healthy, look good, live longer, have more energy, and this will reduce the risk of heart disease. We also learned about the FITT principle. The F stands for frequency, which is how many times you do the act ...

The National Socialist German Workers Party almost died one morning in 1919. It numbered only a few dozen grumblers it had no organization But many among the middle class admired the Nazis muscular opposition to the Social Democrats. And the Nazis themes of patriotism and militarism drew highly emotional responses from people who could not forget Germanys prewar imperial grandeur. In the national elections of September 1930, the Nazis garnered nearly 6.5 million votes and became second only to the Social Democrats as the most popular party in Germany.
