Case Study 1. Dunchenne muscular dystrophy is a genetic disorder due to progressive weakness and degeneration of muscle cells over time‚ discovered by Guillaume Duchenne. 2. What you may notice under microscopic view is a mass majority of adipose tissue‚ rapid growth of Endomysium connective tissue‚ and deterioration of muscle cells 3. Being diagnosed with the disease would show pelvic muscle being effected first. Early signs of muscular dystrophy would be fatigue or weakness in the gluteal

Principles of Muscular Flexibility The overload and specificity of training principles also apply to development of muscular flexibility. To increase the total range of motion (ROM) of a joint‚ the specific muscles surrounding that joint have to be stretched progressively beyond their accustomed length. The principles of MODE‚ INTENSITY‚ REPETITIONS and FREQUENCY of exercise also can be applied to flexibility programs. 1.MODE OF EXERCISE * BALLISTIC STRETCHING Ballistic stretching is

The muscular system is what is responsible for the way that we move. Without the muscular system‚ we wouldn’t be able to participate in the normal activities that we do today. There are 700 known/named muscles that are attached to the human skeleton. There are three different types of muscle that can be found in the human body. The Visceral muscle which can be found inside organs such as the stomach. This type of muscle is controlled by the unconcious part of the brain. This muscle is also known

Yet the advances of medicine hold out the promise of a possible cure in the foreseeable future with gene therapy. Closer to hand is the possibility that embryonic muscle cells from normal individuals might be injected into people suffering from muscular dystrophy‚ which could bring about partial relief for James and Andrew

activities of daily living. PNF is a type of passive stretching that uses alternating contraction and relaxation movements to increase flexibility. The reason why PNF is better than other forms of flexibility training is that it helps the body’s muscular inhibition. For the elite performer‚ the most useful type of PNF is the CRAC (contract-relax‚ antagonist-contract) technique‚ which uses isometric muscle contractions as its basis. PNF stretching is best performed with a partner. Muscle recruitment

Researchers across the globe have utilized various animal models to study DMD. The most common animal model used to study therapeutics for DMD is the mdx mouse owing to its low cost and easy accessibility. The mdx mouse‚ has a nonsense mutation in exon 23 of the Dmd gene that leads to complete loss of the dystrophin protein 12‚ 13. The mdx mouse model of DMD is not considered an ideal model for understanding the pathogenesis of DMD owing to significant differences in physiology from humans and

Muscular System Animations 1. How do nerve impulses cause muscle contraction? Skeletal muscle is under voluntary control. Nerve impulses that originate in the central nervous system cause muscles to contract. Both neurons and muscle tissue conduct electrical current by moving ions across cellular membranes. A motor neuron ends in a synapse with a muscle fiber. The neuron releases acetylcholine and transfers the action potential to the muscle tissue. The signal will travel through the tissue

If you don’t value them you risk the individual becoming redrawn‚ lacking confidence and upset. Describe the importance of recognising an individual’s strengths
