Multiple sclerosis means "many scars" on the myelin sheath of the central nervous system, and muscular dystrophy refers to muscle weakness and atrophy. Multiple sclerosis affects nerve while muscular dystrophy affects muscle. Some of the symptoms are similar, such as extreme fatigue and difficulty with movement, but MS is an autoimmune disorder that can flare and affect a different area of the CNS each time while MD is a genetic disorder that is progressive and often follows a specific pattern (areas) of muscle wasting.
With MS, disability occurs when the flares are more constant and cause permanent nerve damage to an area of the body, sometimes resulting in being blind, incontinent, wheelchair bound, or even bed ridden. With muscular dystrophy, the disability comes from the lack of stamina due to muscles wasting. Having less and less healthy muscle fibers makes the person exhausted doing simple tasks and eventually can lead to inability to lift, carry, walk, or stand. Falls can happen with both disorders, as healthy nerve and muscle are needed to balance one's body. Falling can result in a secondary disability and recovery is slow and incomplete sometimes. Both of these diseases and their sufferers need our support.

What is the difference between muscle dystrophy and muscle atrophy?
Myasthenia gravis: autoimmune to the ACh receptors at end plate (pathway >>> no muscle contraction) Muscular Dystrophy: genetic (X-linked) defect in dystrophin (pathway >>> myosin-actin crossbridge doesn't form > no muscle contraction)
What is mixed muscular dystrophy?
Mixed Muscular Dystrophy is a rapid progression form of Muscular Dystrophy. This normally occurs to people between the ages of 30 and 50 and death normally occurs within 5 years.
When does bulbospinal muscular atrophy manifest itself?
Bulbospinal muscular atrophy (Kennedy disease) manifests as muscle weakness between the ages of 20 and 40 years.
What is the difference between muscle tone and atrophy?
While they often can be used to indicate the same thing, strictly speaking, "atrophy" means a loss of function due to disuse. "Dystrophy" is more general, meaning "other than normal". The distinction usually comes down to this: something that was originally normal will waste away via atrophy, while something that was never normal to begin with may suffer dystrophy.
What are typical ck levels for muscular dystrophy'?
In muscular dystrophy, creatine kinase (CK) levels are typically significantly elevated, often ranging from 5 to 50 times higher than the normal range. Normal CK levels are usually between 30 to 200 U/L, so those with muscular dystrophy may have CK levels exceeding 1,000 U/L. This elevation occurs due to muscle damage and breakdown associated with the condition. However, CK levels can vary based on the specific type of muscular dystrophy and the individual's age and activity level.
True or false does muscular dystrophy appear between 2 and 6 years of age and progresses slowly?
fales 3-5 years
What are the reasons for a muscle biopsy?
To distinguish between nerve and muscle disorders, to identify specific muscular disorders such as muscular dystrophy , to probe muscle metabolic activities, and to detect muscle infections such as trichinosis and toxoplasmosis.

What is the difference between hypertrophy and atrophy?
Muscular atrophy means that muscle that was there has degenerated. It can happen because of disuse (like if you have a broken bone that's in a cast for a period of time) or because innervation to that muscle has been interrupted (as with a spinal cord injury), or any other reason that it isn't being used. Hypertrophy is increase in the size or number of muscle cells (myocytes). You might say that a bodybuilder or someone with overdeveloped muscles in their arms from using a wheelchair demonstrates hypertrophy, but in a pathological sense, you can also see hypertrophy in muscles in children with muscular dystrophy (getting to that). That happens because of repeated damage to the muscle cells; as long as the body can, it will try to compensate by increasing the size of the remaining cells. Dystrophy means any condition associated with abnormal development. It can be due to malnutrition or to genetic disorders like Duchenne or Becker's muscular dystrophy. Hyper- and hypotonia are, respectively, increase and decrease in overall muscle tone. You can think of them as spasticity or inability to stretch or a tendency to contract and "floppiness" or looseness of muscle tissue or decreased resistance to movement, respectively. They can be due to any number of different disorders; they are very general terms.
What is the difference between cardiovascular endurance and muscular endurance?
cardiovascular =is pig muscular endurance = is cowWTF
What is the difference between muscular disorders and skeletal disorders?
Muscular disorders occur in the muscles while skeletal disorders occur in the bones.
What is the difference between muscular endurance and muscular strength?
The difference between muscular strength and muscular endurance is a matter of what is measured for each. Muscular strength is measured by how much work a certain muscle (or set of muscles) is able to accomplish. Muscular endurance is measured by how much work a certain muscle (or set of muscles) is able to accomplish over a set length of time.
