Which diagnostic studies are most useful for assessing skeletal trauma? Initially‚ x-ray imaging is one of most useful diagnostic imaging to assess skeletal trauma. Based on the impression from the x-ray report‚ an MRI or a non-contrast CT scan may also be useful to assess trauma (Hockenberry‚ & Wilson‚ 2014). III. What are the goals of fracture management

Duchenne Muscular Dystrophy Duchenne muscular dystrophy is a fatal genetic disorder that causes progressive muscle weakness throughout your body. This disorder is caused my mutations in the dystrophin gene. The dystrophin gene is responsible for the production of a muscle protein. So the muscles suffer a loss of protein and contractile fibers. Then the muscles replaced with fat and connective tissue. DMD mostly affects young males exclusively due to an x-linked recessive inheritance pattern

Muscular Dystrophy: any of a group of hereditary diseases marked by progressive wasting of certain "muscles." (Oxford) A general term for a group of inherited disorders which are characterized by progressive degeneration of skeletal muscles. A group of inherited progressive muscle disorders characterized by muscle weakness and eventual death of the muscle tissues. Examples include “Duchenne muscular dystrophy” and “Becker’s muscular dystrophy.” (NCIt) All of the muscles may be affected. Or‚ only

primary functions of muscles? What are skeletal muscles made of? Five Skeletal Muscle Functions 1.Produce movement of the skeleton •By pulling on tendons that then move bones 2.Maintain posture and body position 3.Support soft tissues •With the muscles of the abdominal wall and the pelvic floor 4.Guard entrances and exits •In the form of sphincters 5.Maintain body temperature •When contraction occurs‚ energy is used and converted to heat Skeletal muscles are organs Made of: •Connective

1. Discuss the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Skeletal muscles contain multiple fiber types that are distinguished by their different myosin ATPase speed‚ and the development of their SR. The two main fiber types are type I and type II fibers. Type II fibers have a faster ATPase and a more developed SR than type I fibers. Type II fibers are also part of a larger motor unit‚

Some of the symptoms include fever‚ headaches‚ joint pain‚ swollen spleen‚ and losing weight. To be diagnosed with leukemia‚ your white blood cells would be a high level and all the other blood cell levels would be lower then normal. The treatment for leukemia is chemotherapy( which uses medicine to kill the cancerous cells

Duchenne muscular dystrophy is a muscular dystrophy but in order to understand it and how it works you will need to know about genetics and how they work and after that‚ I can tell you about a few treatments and therapies. Duchenne muscular dystrophy or DMD for short is a mutation that happens in the genes. Duchenne is mostly found in boys and rarely found in girls. Duchenne can be inherited in an x-linked fashion. The symptoms usually appear before the age of 6. Sometimes symptoms can start

Muscular dystrophy (MD) can be described as a group of diseases that cause continuing weakness and loss of muscle mass. (Article 1‚ pg.1) Muscular dystrophy effects homeostasis because abnormal genes (mutations) interrupts the production of proteins that the body needs to form healthy muscle. (Article 1‚ pg.1) The nine major forms of muscular dystrophy are Myotonic‚ Duchenne‚ Becker‚ Limb-girdle‚ Facioscapulohumeral‚ Congenital‚ Oculopharyngeal‚ Distal‚ and Emery-dreifuss. (Article 2‚ pg.1-2) The
