Skeletal and Muscular System Relationship Essay Example for Free

Skeletal and Muscular System Relationship Essay Pinak Patel Anatomy and Physiology Professor Jargen December 14, 2011 Skeletal System and Muscular System In anatomy and physiology we study the structure of living things and the function of living systems. In physiology, the scientific method is applied to determine how different organisms, organ systems, organs, cells, and biomolecules carry out the chemical or physical function that they have in the living system. Both anatomy and physiology are subcategories of biology. Throughout our class we have discussed many different systems of the body. One system that is very important to the human body is the muscular system, which consists of three different types of muscle tissue. Along with the muscular system is the skeletal system, which consists of the bones and the different types of tissue it contains. Both of these systems have many different functions, and can be interconnected together. These two systems work together and they form the musculoskeletal system. The muscular system consists of three different types of muscle tissue and it has four different functions. The muscular system also encompasses many properties. The three different types of muscle tissues it includes are skeletal muscle, cardiac muscle, and smooth muscle. The skeletal muscle’s main function is to move the bones of the skeleton. This muscle is voluntary and is also striated, meaning that it is striped, which is due to the muscle fibers that are combined into parallel fibers. Some of these muscles can be controlled unknowningly. For example, the diaphragm of the human body continues to alternately contract and relax while we are asleep, allowing our lungs to expand to breathe. The cardiac muscle tissue is found only in the heart. It is similar to the skeletal muscle in that it is striated, but it is also different in that it is involuntary. The smooth muscle tissue can be found within the walls of the digestive tract, blood vessels, and airways of the respiratory system. This tissue is nonstriated, which means that it is not striped and the fibers are not arranged into parallel orderly bands like the skeletal and cardiac muscle. The smooth muscle tissue is also involuntary. The muscular system has four key functions. It produces body movements, and stabilizes the body positions, for example, it holds contraction of the neck uscles that hold one’s head upright. Another function of the muscle tissue is that it is the storange and transportation of substances within the body: skeletal muscle contractions move lymph throughout the body, and help return blood to the heart. The final function of the muscle tissue is that it helps to maintain one’s posture. Each skeletal tissue is made of hundreds of t housands of cells called muscle fibers. The fascia is a component of connective tissue and it is a broad sheet of fibrous connective tissue that surrounds and supports muscles and other organs. The external part is the deep fascia that consists of theee layers of connective tissue. The epimysium is the outermost later that encircles the entire muscle. The perimysium surrounds groups of ten to hundereds or more individual muscle fibers, seperating those into bundles called fasicles. Then there is the endomysium, which seperates each individual muscle fiber. The nerve and blood supply of the muscle tissue consists of arteries, veins, and nerves that run together. There are somatic motor neurons that stimulate the muscles to contract. These neurons begin in the brain or spinal cord and extend by an axon to a group of skeletal muscle fibers. All in all, the skeletal muscle tissue contains many vital things, in order for everything to work properly. The skeletal system has many functions as well, just like the muscular system. The skeletal system has six different functions: support, protection, assistance in movement, mineral homeostasis, blood cell production, and triglyceride storage. Unlike the muscular system, posture is not a function of the skeletal system. There are also four types of cells that are present in bone tissue. The first type of cells is the osteogenic cells, which are unspecialized stem cells that are the only bone cells that divide. Another type of cells is the osteoblasts, which are the bone building cells; known as the immature bone cells. Then, there are the osteocytes, which are the mature bone cells and are the main cells in the bone. They exchange nutrients and wastes with the blood, which help maintain the bone’s normal metabolism. Finally, the osteoclasts, which are the cells that release powerful lysosomal enzymes and acids that break down the matrix (resorption). The bone tissue also has nerve and blood supply that also consists of arteries and veins. Although one can claim that there can’t be much inter-relation with the skeletal and muscular system, there are some relations to be made. First of all, vertebrates move by the actions of muscles on bones. Therefore, tendons attach many skeletal muscles across joints, allowing muscle contration to move the bones across the joint. Muscles generally work in pairs to produce movement: when one muscle flexes or contracts, the other relaxes. Next, the skeleton and muscles function together as the musculoskeletal system. This system is often treated as two separate systems, the muscular, and skeletal plays an important homeostatic role: allowing humans to move to more favorable conditions. Certain cells in the bones produce immune cells as well as important cellular components of the blood. Therefore, bone also helps to regulate blood calcium levels, serving as a calcium sink. Finally, the rapid muscular contraction is important in generating internal heat, which is another important function that can relate to bone tissue as well. There are many important systems that we study in anatomy and physiology. The skeletal system and muscular system are just two of them. Both of these systems have many functions that can be studied in depth. Although there are quite a few systems that aren’t very comparable, these two systems make an exception. In conclusion, both of these systems, bones and muscles, work together in many ways and can be inter-related to a certain degree.

Hitler - A Great Leader :: essays research papers

In my opinion, being a good leader firstly he should be able to take full advantage of favorable circumstance, able to rule the country under a chaotic situation. Besides he made attractive promises to gain popular support, skilled in using of propaganda, amoral. Moreover he should have the organizational ability and has the ambition to make his country powerful in the world. In addition, he could use his words to twist and manipulate the minds of people into believing that what he was saying. Using this power, he could get people to do anything for him, which prove his amorality. He should be skillful in carry out successful policy to bring the country to economic prospect, since economy is very important to a country. I think Adolf Hitler is the one. Adolf Hitler was one of the 20th century’s most powerful dictators. He was responsible for World War II and the death of millions. Hitler saw a nation in despair and used this as an opportunity to gain political power. He saw a nation of unemployed and hungry citizens and promised them economic prosperity in return for absolute power. Someone once said â€Å"The Nazis rose to power on the empty stomachs of the German people†. Although he did not live a very long life, during his time he caused such a great deal of death and destruction that his actions still have an effect on the world nearly 50 years later. I am sure that he is a great leader. Adolf Hitler joined a small political party in 1919 and rose to leadership through his emotional and captivating speeches. He encouraged national pride, militarism, and a commitment to the Volk and a racially "pure" Germany. Hitler condemned the Jews, exploiting anti-Semitic feelings that had prevailed in Europe for centuries. He changed the name of the party to the National Socialist German Workers' Party, called for short, the Nazi Party. By the end of 1920, the Nazi Party had about 3,000 members. A year later Hitler became its official leader Fà ¼hrer. From this, we can see his potential of being a leader and his development in his propaganda. In about 1923 Adolf Hitler's attempt at an armed overthrow of local authorities in Munich, known as the Beer Hall Putsch, failed miserably. Hitler, were subsequently jailed and charged with high treason. However, Hitler used the courtroom at his public trial as a propaganda platform, ranting for hours against the Weimar government.

American History Essay

â€Å"The sad truth is that most evil is done by people who never make up their minds to be good or evil† was a wise phase once uttered by Hannah Arendt. I love this quote because is perfectly describes the two boys from â€Å"American History X,† Danny and Derek. These two boys have seen and done it all when it comes to hate groups, as both were members of a neo-nazi hate group. Neo- Nazi hate groups use authoritarian, scapegoat, normative, and exploitation theories to justify their hate, discrimination, and torture of anyone who isn’t a part of the â€Å"supreme race,† or white. Boy Danny and Derek end up in this life from an early age. Parents are one of the biggest, if not the biggest influence on a child’s life. When Danny and Derek were both relatively young they looked up to their father, thought of him as the â€Å"ideal† man. However their father was a racist, influencing almost every thought the boys had. At family dinner when talki ng about about a black school teacher their father said, â€Å"It’s nigger bullshit,† and warned Derek not to buy into the equality teachings. Because Danny and Derek both looked up to their dad so much, this would be and example of the exploitation theory. Exploitation theory is when one societal group, in this case whites, use hostility to keep their position and power intact. This really come into play after Danny and Derek’s father was murdered and Derek believes it was a race related killing. Right after their father died, Derek joined a neo-nazi hate group known as the DOC(Disciples of Christ). Being extreme believers in the white supremacy movement, the DOC acted out with violence and extreme hatred toward any other race, especially blacks. Derek, being a high ranking member, murdered 2 black men for the cause. He served three years for the murders, which impacted his whole family tremendously. At the beginning of Derek’s sentence he did not want any visitors, claiming it would be to hard to see his family. He made friends with other neo-nazi members in prison, but soon started realizing that they were not serious about the cause like he was. He also started becoming friends with his black work partner who said, â€Å"I ain’t the nigger in here, you are† Derek started realizing that white supremacy what basically just a scapegoat. Meaning that the followers of the movement were just trying to find someone to blame for their problems, which in this case happened to be  the blacks. After befriending his black work mate he realized that blacks are human too. Once he could recognize blacks as human he finally felt guilt for killing to people, not niggers, people. Derek was determined to help his brother and family by getting them out of the gangs and hate. One of the biggest influences on Derek while in jail was his principal from high school. He was a black man with experience in dealing with â€Å"troubled youth.† He gave Derek the push he needed by saying, â€Å"Has anything you’ve done made your life better?†. Later Derek told Danny, â€Å"It’s just because I was pissed off†. I think this was Derek’s way of responding to his principal, he really didn’t believe in the cause it was more of just an outlet for his anger that his father would have approved of. While Derek is locked up.
