What occurs when a muscle becomes smaller and weaker from not being used?
shrink in size and lose strength
What is paraspinous atrophy?
Atrophy is the reduction in size and therefore strength of a muscle. This often occurs due to prolonged disuse or malnutrition, but several other causes are possible. Paraspinous atrophy simple refers to the loss of muscle mass in the area surrounding the spine.
What is the medical term meaning disuse of muscles over a long period of time?
Muscular atrophyThe term you are probably looking for is atrophy. Atrophy is a weakening of the muscles that occurs after long periods where they are not used. It doesn't describe the time period, but rather the result.
Why does the body lose muscle?
Muscular atrophy occurs with starvation and disuse. (Or as those of us in the fitness community like to say, "use it or lose it!")
What causes lost of muscle mass?
Muscle mass loss can be caused by lack of exercise which is referred to atrophy and disease known as sarcopenia.
What is diffuse global atrophy?
Diffuse global atrophy, or diffuse brain atrophy, is when the brain shrinks in size. It's more severe than the atrophy that occurs normally with aging.
What is global diffusion?
Diffuse global atrophy, or diffuse brain atrophy, is when the brain shrinks in size. It's more severe than the atrophy that occurs normally with aging.
What are the Causes of atrophy of frontal cerebrum?
Atrophy occurs when a muscle loses its mass and strength. This is caused by inactivity in the muscle, which causes the body to restrict blood flow to it to allow blood to be used more efficiently elsewhere. And since the muscle isn't being exercised either, it is not tearing and regrowing, and it begins to shrivel up onto itself.
Muscle atrophy?
DefinitionMuscle atrophy is the wasting or loss of muscle tissue.Alternative NamesMuscle wasting; Wasting; Atrophy of the musclesConsiderationsThere are two types of muscle atrophy.Disuse atrophy occurs from a lack of physical exercise. In most people, muscle atrophy is caused by not using the muscles enough. People with sedentary jobs, medical conditions that limit their movement, or decreased activity levels can lose muscle tone and develop atrophy. This type of atrophy can be reversed with exercise and better nutrition.Bedridden people can have significant muscle wasting. Astronauts who are away from the Earth's gravity can develop decreased muscle tone and lose calcium from their bones after just a few days of weightlessness.The most severe type of muscle atrophy is neurogenic atrophy. It occurs when there is an injury to, or disease of, a nerve that connects to the muscle. This type of muscle atrophy tends to occur more suddenly than disuse atrophy.Examples of diseases affecting the nerves that control muscles:Amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease)Guillain-Barre syndromePolio (poliomyelitis)Although people can adapt to some degree of muscle atrophy, even minor muscle atrophy usually causes some loss of movement or strength.Common CausesSome muscle atrophy occurs normally with aging. Other causes may include:Alcohol associated myopathyAmyotrophic lateral sclerosis (ALS or Lou Gehrig's disease)BurnsDermatomyositisand polymyositisGuillain-Barre syndromeInjuryLong-term corticosteroid therapyLong-term immobilizationMotor neuropathy (such as diabetic neuropathy)Muscular dystrophyOsteoarthritisPolioRheumatoid arthritisSevere malnutritionSpinal cord injuryStrokeHome CareAn exercise program (under the direction of a therapist or doctor) is recommended to help treat muscle atrophy. This may include exercises in water to reduce the muscle workload, and other types of rehabilitation.People who cannot actively move one or more joints can do exercises using braces or splints.Call your health care provider ifCall your doctor for an appointment if you have unexplained or long-term muscle loss. You can often see this when you compare one hand, arm, or leg to the other.What to expect at your health care provider's officeThe doctor will perform a physical examination and ask questions about your medical history and symptoms, including:When did the muscle atrophy begin?Is it getting worse?What other symptoms do you have?The doctor will look at your arms and legs and measure muscle size to try to determine which nerve or nerves are affected.Tests that may be performed include:Blood testsCT scansElectromyography (EMG)MRI scansMuscle or nerve biopsyNerve conduction studiesX-raysTreatment may include ultrasound therapy and, in some cases, surgery to correct a contracture.ReferencesBarohn RJ.

What is the term for the break down of muscle tissue?
Myolysis is the medical term meaning breakdown or degeneration of muscle tissue. When you lots of cardio sessions. It occurs when the muscle don't have fuel , and the fat storage it's could be used , but the proteins are easyer to breakdown...myolysisMyolysis.
What is suprascapular nerve entrapment?
a rare type of entrapment syndrome that most often occurs in athletes. The major symptom is a dull pain near the shoulder blade, which can progress to weakness and muscle atrophy.
What kind of fermentation occurs in the muscle during rapid exercise?
lactic acid
