What is the difference between muscle dystrophy and muscle atrophy?
Amandaerasmus39
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)

∙ 10y agoThe difference between muscle atrophy and dystophy is that the atrophy is a wasting away of muscle due to disease or poor nutrition. Muscle dystrophy is degeneraion of muscles or any organs in the body caused by a disease process, or it can also be caused by malnourishment.

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 is the medical term meaning progressive atrophy or weakening of a body part such as the muscles?
myolysisrhabdomyolysis is the breakdown of muscle fibers. This releases the contents of the fibers into the blood stream. Rhabdomyolysis can be caused by damage to the muscle itself.Muscular AtrophyDegeneration of muscle tissue is known as myolysis.
What is the difference between spinal muscle atrophy and muscular dystrophy?
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 happen if muscles are not used?
if the muscle are not used they become weaker and smaller than normal size ,but this problem is reversible by more physical exercises until the muscles aren't damaged. but if the denervation or injury occur to the muscle the weakness could be persistent and atrophy may occur.
What is muscle atrophy?
Muscle atrophy refers to the wasting or loss of muscle tissue resulting from disease or lack of use.
When a muscle is not used and it grows smaller that is called?
Disuse of a muscle causes atrophy, which is a shrinking of muscle fibers leading to weakness. With use, the atrophy can be reversed.
Does atrophy of muscles cause a increase in size?
atrophy is a decrease in muscle mass. Hypertrophy is muscle growth.
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 diuse atrophy?
diuse atrophy (muscle loss or weakness from lack of use)
What two prominent muscles are affected in muscle atrophy?
Muscle atrophy can affect any muscle within the body. Atrophy is a wasting or decrease in size of a body organ, tissue, or part owing to disease, injury, or lack of use. Any muscle is subject to atrophy from either lack of use or disease. This is especially true after injury or extended bedrest. To answer your question there are no two prominent muscles that are exclusively affected in muscle atrophy.
What is the degeneration of muscle tissue?
Atrophy
When a muscle deceases in size?
atrophy
