Duchenne muscular dystrophy is a genetically inherited disease that causes progressive muscle and bones weakness. The symptoms usually appear before age 6 and may appear as early as infancy. Symptoms can be noticed very early like not sitting and standing independently at the correct age. The age for walking for boys with Duchenne muscular dystrophy is around 18 months. There is progressive muscle weakness of the legs and pelvic muscles‚ which is caused by a loss of muscle mass. This muscle weakness

Introduction Duchenne Muscular Dystrophy is a dangerous and rare disorder. It’s transferred through family generations because it’s a genetic disease. In addition‚ Duchenne Muscular Dystrophy is referred to by other names including DMD‚ Duchenne Syndrome‚ and Pseudohypertrophy. DMD is when the body cannot make dystrophin so it results in muscle weakness. Mode of Inheritance Duchenne Muscular Dystrophy is an X-linked recessive disorder and that’s why it’s more common in males. As for females‚

Muscular Dystrophy‚the progressive loss and weakness of muscle‚is a muscular disorder first described in the 1860’s by a french neurologist .The term Muscular Dystrophy encompasses any type of dystrophy of muscles‚about nine different types.The most common type is Duchenne Muscular Dystrophy which makes up approximately half of muscular dystrophy cases. Muscular Dystrophy is most present in boys‚but girls may also carry the gene‚although they usually show no symptoms.In 2007‚ it was revealed that

Great job once again on answering the question about how muscle action relates to the movement. I think maybe I took it to the extreme‚ I went on about agonist‚ synergist‚ and antagonist muscles. I wasn ’t sure if I should add the levers too. It appears as though you explained every type of muscle movement and gave an example of each. I went into flexion at the elbow and discussed that the agonist is the main muscle mover‚ the antagonist does the opposite‚ and the synergist is the helper. However

Purpose What is the purpose of this exercise? The purpose of this exercise is to learn the skeletal systems and the components associated with the system. I will be exploring the major types of bones and cartilage. Are there any safety concerns associated with this exercise? If so‚ list what they are and what precautions should be taken. Handle the microscope and the slides with care; when taking the chicken bone out of the oven use caution because the bone is extremely hot. Exercise

Muscular Disorders Case Report Case: A mother presents with her 13 y/o son with a history of frequent falls‚ difficulty getting up from a lying or sitting position‚ trouble jumping‚ large calf muscles and poor grades in school. Based on the description and symptoms given‚ the likely diagnosis would be Duchenne’s muscular dystrophy‚ or DMD; although DMD and its symptoms tend to show up at an earlier age but not always. This type of muscular dystrophy is the most common and severe form of

The Game of Badminton When you think of badminton‚ what do you think of? Do you see sweaty old women playing a game before their trip to the local bingo? Or maybe you imagine a weak little old man who has to stop playing because he got a bit excited and needs a sit down before his heart packs in? Well‚ I’m afraid you’ve got it all wrong! They’re just myths! Throw them all away and grab hold of some facts! The truth about Badminton [IMAGE] It’s an indoor game so the rain won’t

In this lab report I will be talking about exercise 3‚ the skeletal muscle lab. I will be going over the contraction of a frog’s gastrocnemius muscle. An overview of muscle contraction is based on the organization of the cytoskeletal proteins. The contraction is the shortening of a sarcomere‚ which is caused by the thick myosin filaments sliding past the thin actin filaments. The actual filaments aren’t getting shorter just sliding past each other. The contraction is caused by physical interaction
