The muscular system’s main function is movement. Muscles are the only tissue in your body that can contract and move other parts of the body. The second function of the muscular system is the maintenance of posture and body position. The muscles responsible for the body to have the greatest strength of all muscles in the body. The last function of the muscle tissue is the generation of body heat. Our muscular system processes a great deal of waste heat.Muscles contract to hold the body still or in position rather than to cause movement. The cardiac and visceral muscles are responsible for transporting substances like blood or food from one part of the body to the other.
Many small muscle contractions within the body produce our natural body heat. When we sweat more than normal, the extra muscle contractions lead to a rise in body temperature. The 650 muscles in our body not only supports movement, controlling walking, talking, standing, eating, and other daily functions. Muscles make up more than half of the weight of the human body. People who do heavy weight training often gain weight because muscles are about three times as dense as fat. Some of the biggest muscles are in the back, near the spine. They are responsible for keeping the body upright and gives the body the power it needs to lift and push things. The muscular system is broken down into three types of muscles, skeletal, smooth and cardiac. Not only do muscular disorders affect mobility, but can result in many other functional abnormalities, such as the inability to breath, swallow or speak. The muscular system impacts so many of the functions necessary to sustain life. Some muscles help pumping blood to the heart, some help you digest, and others help you move. Hum...

...ufficiently nourish the organs. This blood flow shortage causes severe damage to organs and tissue. Symptoms of cardiomyopathy include shortness of breath and other breathing difficulties, fatigue, swollen legs and feet, and irregular heartbeat. It can lead to heart failure.
The muscular system is important in the daily life to the humans. The muscular system is the body's network of tissues that control movement of the body. Walking, running, and jumping, all of these actions propelling the body through space are possible only because of the contraction and relaxation of muscles. These movements, however, are not the only ones directed by the muscular activity. Muscles make it possible to stand, sit, speak, and blink. Even more, were it not for muscles, blood would not move through the digestive system. Muscles are the machine of the body, allowing it to work.
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections
Emery-Dreifuss muscular dystrophy is a rare form of muscular dystrophy characterized by early onset contractures of the elbows, achilles tendons and post-cervical muscles with progressive muscle wasting and weakness It is also associated with heart complications like cardiomyopathy and arrhythmia which in both cases can lead to death. Cardiomyopathy is a heart disease which affects the muscles of the heart. In cardiomyopathy is muscles get rigid, enlarged or thick. They also sometimes changed by scar tissues. On the other hand arrhythmia is a disorder with the rhythm or rate of heartbeat. The heart can beat fast, which is called tachycardia or it could be beating too slow, which is called bradycardia. Emery-Dreifuss muscular dystrophy is characterized by early onset of contractures and humeroperoneal distribution. Humeroperoneal refers to effects on the humerus and fibula. The genes known to be responsible for EDMD encode proteins associated with the nuclear envelope: the emerin and the lamins A and C.
The skeletal system assists the muscular system to provide movement for the body. Certain muscles that are attached to bones contract and pull on the bones resulting in movement.
They support and bind tissue and organs together. Primary function is to support the body, allow motion and protect vital organ. The skeletal system and muscular system are two separate systems that function together. It provides movement, maintains posture, and body position. They work together through a series of impulses and signals communicated by the brain. In order for movement to happen, the nervous system signals the skeletal muscles to contract. When the muscles contract, it causes the attached bone to follow, creating movement. Bones and muscles are supported by connective tissue playing the role in structural
Every part of our body is a science. I never imagined the hidden science in the movements of the body. The science of kinesiology is the science of body movements. I grew up watching my grandma and the changes in her body as both of us got older, I could walk and balance properly while she lost it. I always felt bad when she was not able to get up and walk properly and as caring grandson I always gave her my hand. It was a great feeling for me to take care of her in her last days. Her difficulty in moving always pointed me to do something for her and I landed doing kinesiology- the science of human movements. I completed my high school at Cathedral High School in West Texas. I was an active member of National Honor Society as well as Spanish Honor Society. I held the treasurer position for one year in the society, which I felt proud of. I was not excellent at my academics, was just an average student struggling with the subjects of chemistry and anatomy. It is strange at one point of time suddenly when u come across a certain situation or an accident and u just realize your dream and...
The Skeletal system performs vital functions; supports movement, protection, blood cell production, calcium storage and endocrine regulation. That enables the human body to survive.
It is estimated that 1 out of every 5,600-7,700 boys ages 5-24 have Duchene or Becker muscular dystrophy. (“Data & Statistics,” 2012 April 6) Muscular dystrophy is a group of genetic diseases defined by muscle fibers that are unusually susceptible to damage. There are several different types of muscular dystrophy some of which shorten the affected person’s lifespan. (“Muscular dystrophy: Types and Causes of each form,” n.d.) There is a long history of the disorder but until recently there wasn’t much knowledge of the cause. (“Muscular Dystrophy: Hope through Research,” 16 April 2014) Symptoms are obvious and can be seen as soon as a child starts walking. (“Muscular Dystrophy,” 2012 January 19) Although muscular dystrophy mostly affects boys, girls can get it too. (“Muscular Dystrophy,” 2012 January 19) There is no cure for muscular dystrophy but there are several types of therapy and most types of muscular dystrophy are still fatal. (“Muscular Dystrophy: Hope through Research,” 16 April 2014)

Bradycardia can be very serious. Some of the symptoms are loss of consciousness, heart failure, or death. Slow heart rates are caused by heart block. The hearts natural pace-maker fails to be conducted to the ventricles, the hearts main pumping chambers.
The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
Muscles are very vital to the human body and as seen above mankind could not survive without this system. It helps for energy, movement, temperature stabilization, pumps blood, and keeps everything working properly as well as many more things. Muscles don’t just do it all by themselves though, muscles work with every other system in the body especially the nervous system because that is were in gets all of its impulse signals from the brain so that the muscle are able to do the things they are capable of.
The history of anatomy and physiology dates back to ancient Egyptian times when humans were mummified after death and bodies would be stripped of their internal organs during the embalming process. It was not until much later when Hippocrates II, known as the father of medicine, was the first to write about human anatomy. Shortly after that, the Alexandrian Medical School was established, where human dissection was allowed for the first time, which promoted research and new discoveries in the field. From there, many other influential researchers came up with theories regarding the cardiovascular and nervous systems, etc; however, the missing links in some of the earlier theories was found with the discovery of the microscope, which changed the focus of research and led to many advancements in the field.
Support is a very important fuction as without the skeleton the body would have no means of staying upright as almost all of the body tissues are soft this helps gives the body structure. The Skeleton plays an important role in the protection of the organs for example the skull protects the brain and the ribcage protect the lungs.The skeleton assists in the movement of the body as the ligaments in the body attach bone to bone and the tendons attach muscle to bone. To create movement the muscular system and the skeletal system work together creating the musculoskeletal. The skeleton can begin to move once the muscles contract. The fifth function of the skeleton is the formation of joints, these are essential to create movement within the body. Muscle attachment allows the bones to move. This is done by the muscles attaching to the bones by tendons. Minerals such as calcium salts and phosphorus are stored in the bones. The final function of the skeletal system is the formation of blood cells; most of the blood cells for the body are produced by red bone
