The muscular system's structure is made up of thousands of small mussel fibers. These mussel fibers make up our mussels. The mussels you have on one side of your body are there on the exact same spot on the other side, with a few exceptions like the heart.

The muscular system is the support system that responsible for our movement. It uses the skeletal system as an anchor, and the muscles pull on those bones. Most of our body heat is from our muscle contractions. The Muscular system is a core part of us. Without it, we could not live our every day lives. The muscles themselves also give our body shape.

Polymyostis is a inflammatory disease that affects muscles on both sides of your body. It makes those muscles very weak, making it hard to do everyday tasks, like climbing stairs. Your muscles can become so weak, that you can barely use them. Polymyostis does not occur overnight, it is a gradual effect that will build up over time. It is important that if you feel severe muscle fatigue, that you go seek professional help.

Joyce Ma started to feel muscle fatigue one day, but she ignored it. She kept ignoring it until one day, she was so weak she could barely lift her arms. She went to her doctor, who told her to go to another doctor who said the had polymytosis. Two years later, she was able to control her disease, and her medical dosages were lowered. She was able to overcome polymytosis, and she regained her muscle strength. They are now officially off of the medications, and they have overcome polymytosis.

Physical therapists evaluate and record the progress of their patients. They help the injured or elderly regain muscle strength. They are often part of rehabilitation and preventive care. The average physical therapist makes 88k-150k a year. To make that much, you need 6-7 years of training to become one, not including the 4 years of undergraduate studies. The work setting includes you with your client, and possibly with other patients or physical therapists.
