Understanding muscular dystrophies in anatomy and physiology is very essential and influential when determining the different types of diseases it carries. Muscular dystrophies are groups of different inherited diseases that causes weakness and loss of the muscle. There are over 30 many different types of muscular dystrophies that carry different types of symptoms and severity (Martel, 2015). If you’re inherited with any type of muscular dystrophies, your muscles begins to worsen, as you grow older to the point where the ability to walk might be lost. Some forms of muscular dystrophies appear in infants and children while others appear in a later age. The three main common muscular dystrophys are Duchenne muscular dystrophy, Becker muscular …show more content…
The DMD gene is approximately located on the “X” chromosome and BMD follows x-linked recessive inheritance. Females carry two chromosomes but one of them is shut down and then all the genes on that chromosome are inactivated. Females who carry disease genes on one of their X chromosomes are known as carries for the disorder (Bushby, 1993). When it comes to male chromosomes you’ll be able to find one X-chromosome and if that male begins to inherit an X chromosome that contains the disease gene, that male will begin to develop the disease. Female carriers who have an X-linked disorder have a 25% chance with any pregnancy to have a carrier daughter just like them, a 25% to have a non-carrier daughter (Bushby, 1993). The same goes for male born individuals with a 25% chance of being affected and a 25% of being unaffected. 1 in 30,000 male births are affected by becker muscular …show more content…
Physical and occupational therapy reduces and delays joint contractures. Surgery depending on how the disease is affecting the individual is recommended to treat scoliosis and contractures. A big factor is weight control and by this exercising and being active can really help reduce the stress on the heart and muscles. Myotonic dystrophy is very complex in the meaning that there are different stages of it. Myotonic diseases are a heterogeneous group of genetically determined diseases that are structured by the visibility of myotonia. This is defined as an unsuccessful relation of the muscle after its activation (Salajegheh, 2016). The presence of these diseases can range from asymptomatic electrical myotonia, to many different disabilities with the weakness of muscles, cardiac defects and other systemic features as in dystrophy type I known as

Duchenne Muscular Dystrophy

Duchenne muscular dystrophy, also known as DMD, is a genetic disorder characterized by progressive muscle weakness and degeneration. Duchenne muscular dystrophy was first described in the 1860s by Guillaume Benjamin Amand Duchenne, a French neurologist but until the 1980s, little was known about the cause of any kind of muscular dystrophy. This disease is x-linked recessive. Approximately two-thirds of DMD occurrences are hereditary while one-third of cases are due to a new mutation. It is one of…

Duchenne Muscular Dystrophy Essay

Duchenne Muscular Dystrophy (DMD) is a genetic disorder, primarily affecting muscles. It is also known as pseudohypertrophic muscular dystrophy. DMD is named after Guillaume Benjamin Amand Duchenne, a 19th century French neurologist. Some symptoms of DMD include weaknesses in the pelvis, upper limbs, heart, back and muscles around your lungs. There is also fatigue, mental retardation and difficulty with motor skills associated with the disease. These symptoms may cause frequent falling and clumsiness…

Muscular dystrophy refers to a group of genetic (inherited) conditions that cause the body's muscles todeteriorate slowly over time, and become increasingly weak. Some of the signs and symptoms ofMuscular dystrophy are: problems with coordination and mobility with frequent falls, muscle weakness, and joint stiffness. High levels of a chemical called creatine kinase (CPK) found in the blood may alsohelp diagnose muscular dystrophy. High levels of creatine kinase don't give a definite diagnosis, sincemany…

Duchenne muscular dystrophy (DMD ) is a muscle disease that includes muscle weakness and can be inherited and can gradually worsen over time. It’s caused by a defective gene and it affects more boys than girls, but the girls can be carriers for the disease. Many young infant males are affected by this disease, and, as time passes, they start to develop symptoms (University of Maryland Medical Center (UMMC), 2014). DMD is a muscular disease that is inherited and causes muscle weakness . What is…
