Like the previous responders said, there are many. Here are a few more.

  1. Lou Gehrig Disease-Another name for Lou Gehrig disease amyotrophic lateral sclerosis (ALS). When a person has ALS it means that motor neurons has begun to shrink and the muscles are no longer being told to move. Over time, the body becomes paralyzed.
  2. Botulism-Botuism occurs from a neurotoxin coming from the bacteria Clostridium botulinum. When a person becomes infected, they experience paralysis.
  3. Tetanus-Tetanus also occurs because of a bacterial (Clostridium tetani) infection. This bacteria infects a wound and produces a neurotoxin which affects the muscles and nerves, causing muscle spasms. Another name for tetanus is lockjaw.

Since some diseases of the muscle are caused by bacteria, it is always important to keep wounds clean. In addition, exercise is a great way to keep the muscles toned but they do need adequate rest as well. It is also important to drink lots of water to stay hydrated.

There are too many diseases that effect the muscular system to mention.  Many of them are brain disorders that effect the motor control areas in the frontal and parietal lobes of the brain.  To name some:

Muscular dystrophy - genetic disease that renders muscle fibres more vulnerable to damage than normal

Dermatomyositis - autoimmune disease causing skin rash and muscle weakness

Compartment Syndrome - the result of too much pressure building up around the muscles causing severe pain and sometimes cellular death

Rhabdomyolysis - causes muscle fibbers to breakdown and get absorbed into the bloodstream, alcoholism, drug abuse, and heatstroke are several known causes

Fibrodysplasia Ossificans Progressia - rare congenital disease that causes the muscles, tendons, and ligaments to be replaced with bone tissue

If you want to keep your muscles system healthy you should:

Exercise on a regular basis
Eat a balanced diet
Consume  a sufficient amount of Vitamin E

Hundreds of musculoskeletal diseases and disorders afflict us, some are quite minor, others can cause severe, unrelenting damage. A few are as follows:

1. Myasthenic gravis is a motor disorder with an autoimmune component. It develops from repetitive muscular use. A hallmark is muscle fatigue.

2. Multiple sclerosis is an autoimmune neuromuscular degeneration caused by demyelination of motor neurons. It is characterized by a progressive loss in muscle function.

3. Spasmodic torticollis is a seizing of the muscles of the neck and or shoulder caused by remaining in one position for extended periods of time. It is characterized by an inability to turn the head.

Maintaining good muscle health is similar to maintaining good general health. You should eat a balanced diet, exercise routinely, and get proper amounts of rest.

Many muscle diseases do not have cures at this time. This is why you have to be very aware of your body, so if something is not right you will notice it. Two of the most common muscular diseases are Muscular Distrophy and ALS. They can be progressive, meaning they get worse over time.

Muscular atrophy

It occurs most frequently in muscles that are not used frequently. The muscles reduce their size and lose their strength.


The myalgia term defines the muscles' pains and it is characteristic of many muscular and skeletal disorders. It can occur in aparticular muscle, or in the whole body. Myalgia may be acute or chronic.

Flat feet

Flat feet disorder occurs due to the weakening of the leg muscles located in the curvature of the sole. Flat feet is of two types: flexible and rigid. Flexible flat feet is usually asymptomatic and it is not painful.


Is a rupture that occurs in a weak region of a muscular wall. There are many types of hernia. The most common is abdominal hernia, when the abdominal muscular wall is torn and intestines enter through it. This can happen in different regions of the abdomen. Hernia has different names, depending on it's location.

Muscle hypertrophy

Is the result of excessive exercises, bodybuilding type. The diameter of the muscular fiber or the size of the muscle are growing.

The number of diseases that may affect the muscles are too many for all to be described on this forum. But have described below some of the common disorders of the muscles.


Occasionally, a person may experience painful cramps of certain skeletal muscles if he or she exercises too hard or for a long time. Cramps also may develop in smooth muscle organs, such as the stomach and intestine. Skeletal muscle cramps involve sudden and violent muscle contractions. A severe muscle cramp may continue for several hours or even days if untreated.  Exact cause of the cramps is not known.  They are probably caused by too much or too little salt in the fluids surrounding muscle fibres.

Muscular Atrophy Disease:

This diseases attack and damage the nervous system, including nerves that stimulate muscles.  As a result, muscles progressively shrink and become weak.  Motor neurone disease is an example of an atrophy disease.

Duchenne muscular dystrophy:

This is a disease most common and most rapidly progressive of the childhood muscle diseases.  Usually, the first sign of the disease is difficulty in walking at an early age (from 2 to 6 years).  When it develops further, Walking and standing become more difficult, and the patients fall frequently and cannot run. The disease eventually spreads to most muscles of the body.  Duchenne dystrophy is an inherited disorder that affects only boys.
Facioscapulohumeral dystrophies:

This disorder progresses slowly and usually become evident in adolescence or early adult life.  it affect both men and women.  Most patients have a normal life expectancy, though with increasing disability.

This disease primarily affects the muscles of the face, shoulder, and upper arm.  It is inherited as a dominant gene abnormality.

Limb-girdle dystrophy:

Like facioscapulohumeral dystrophiy this disorder also progresses slowly and usually become evident in adolescence or early adult life.  It affect both men and women and primarily affects the muscles of the arms, shoulders, legs, and hips.  The condition is inherited as a recessive gene abnormality.


Muscular weakness also occurs in this disease. However, weakness results because the muscle itself does not function properly.  Certain myopathies, such as various muscular are characterized by gradual wasting away of skeletal muscles.

Keeping Muscles Healthy:

Best way to keep muscles in good health is to use the muscles regularly. However it is important not to over exert the muscles. the strength of muscle can be improved by regular and progressive exercise. However exerting the muscle beyond its capacity can damage it.

Also it is important to take adequate rest to overcome the effect of fatigue, and allow any wear and minor damage to the muscles to be repaired.

A health and balanced diet is also important for good general health including the health of the muscles.

There are many diseases which afflict the muscular system. Here are three of them:

  • muscular dystrophy- this is a group of genetic diseases that cause the muscle fibers to become easily damaged.
  • Rhabdomyolysis- this damages the muscles and as the muscles degrade they release a chemical called myoglobin, which blocks the kidney structures and can lead to kidney failure
  • Dermatomyositis- This is an autoimmune disease which causes muscle weakness and may lead to difficulty in swallowing, muscle pain, ulcers, fever, fatigue and weight loss

A few ways recommended to keep the muscular system healthy include:

  • doing aerobic activity or activity that engages the heart and lungs for at least 30 minutes at a time, four or more days a week.
  • reducing the consumption of alcohol, and eating a well-balanced and nutritional diet
  • reducing physical and emotional stress, a few common ways of doing this include deep breathing when you find yourself in a situation that leads to anger; yoga; meditation and proper sleep.
