The Mysteries of the Muscular System By Max S. and Livie M.

Major Organs in Your Body System with Labeled Diagram What are: the cells (specialized, how many different kinds?)the tissuesThe muscular system has 3 distinct organs the skeletal (biceps), the cardiac (heart), and smooth muscles (stomach). A muscle consists of muscle fibers, connective tissue, nerve tissue and blood tissue and is considered one organ.System OverviewThe muscular systems job is to help the body move around. Your body has more than 600 muscles in total. The muscular system also helps keep your body warm because your body is always moving, and your heart pumps out blood and the blood is always warm. The human muscle system is a network of tissues which control movement of the body.

Major OrgansThe muscular system has 3 distinct organs the skeletal (biceps), the cardiac (heart), and smooth muscles (stomach). A muscle consists of muscle fibers, connective tissue, nerve tissue and blood tissue and is considered one organ. The cardiac muscles help the heart pump blood. The skeletal muscles, also the voluntary ones, help move your body. The smooth muscles are in your digestive tract, and help digest or regurgitateHow does that job keep your body just right (homeostasis)?

Muscular system keeps the body just right, because it helps maintain 98.6 F. 98.6 F, or 37 C, is an average body temperature, and the muscles inside your body help warm yourself up, or cool off when your blood vessels dilate and inflate. If it wasnt for your muscular system, not only would you be incapable of any basic functions, but you would also either be very hot, or super cold.Muscular System Video

Diseases and Disorders These are only a few of the many diseases affecting your muscular system. Most diseases relating to the muscular system decrease your mobility. Articles say to getimmediate medical help if having symptoms of any of these diseases. Some of these diseases include:Muscular Dystrophy: causes damage to the skeletal muscular fibers, resulting in weakness and loss of coordination. There is no specific cure for this disease.Cerebral Palsy: affects your posture and balance. Usually is transmitted to children born with brain damages.Fibrodysplasia Ossificans Progressiva: causes the muscles, tendons, ligaments as well as other connective tissues to grow bones between the joints. There is no treatment for this disease so pain medicine is used.Dermatomyositis: leads to chronic muscle and skin inflammation. Some symptoms include muscle pain, lung problems, fever, fatigue and weight loss.Myasthenia Gravis: results in muscle weakness and fatigue. Medications and surgery are part of the Myasthenia Gravis Treatment.Myopathy: cause the skeletal or voluntary muscles to become weak or wasted.

Keeping the Muscular System HealthyIt is very important to keep your muscles healthy, because they help you keep warm and provide you the ability to move. Experts say that one of the best ways to keep your muscular system healthy is to work out with weights. Strength training will help improve your muscle strength and endurance. Another good way to strengthen your muscles is hiking. When hiking, your big and small muscles are exercised by utilizing oxygen. Most people should be exercising for at least 45 minutes a day, every day, to keep your muscles very healthy. With healthy muscles, youll become strong, athletic and very capable of long-endurance exercising.

LIFTING WEIGHTSScientific Breakthroughs One of the major scientific breakthroughs is prosthetics. Prosthetics are artificial extensions used in the limbs. They replace missing body parts commonly removed by war. One of the main reasons prosthetics were invented was because of war. Soldiers would come back severely wounded, many needing amputation.Interesting Facts and TriviaIt takes almost 3x as many muscles to frown, then to smileMuscles can be longer than a foot long40% of your weight is made up of musclesThe hardest working muscle is the one in your eyeThe body comprises of over 630 musclesScientists believe that eye muscles move more than 100,000 times a dayThe three types of muscles are smooth muscles, skeletal, and cardiacMuscles work in pairs: one muscle moves the bone, and the other moves it backWithout muscles, you cannot liveEveryone has the same amount of musclesLack of oxygen causes muscles to stop workingThe cardiac muscle is found only in the heartSmooth muscles are found only in internal organsSkeletal muscles are voluntary muscles, meaning you can move them whenever wherever you wantSmooth muscles are involuntary muscles, meaning that they move automatically, without you having to tell themTest question for your classmates?What are the three main types of muscle tissue in the human muscular system?Name an example of a muscle in each type of muscle tissueWhat is a common invention used to replace limbs?Name two diseases affecting the muscular system.
