Do doctors learn all muscles?

The main function of the muscles is to help the body move. Muscles work in pairs and together to form a complex system of joints, muscles, and bones that allows for the movement of the body. When a muscle contracts, it tightens the muscle fibers. This makes the joint move. When the muscle relaxes, it stretches the muscle and the joint moves.

Each pair of muscles is attached to a joint. For example, your knee and thigh muscles are attached to your knee joint. Your leg muscles and arm muscles are attached to your arm joints.

The muscles that help the body move are called skeletal muscles. Other muscles, such as those in your chest, abdomen, and pelvis, are called smooth muscles.

Muscles can work in different ways. For example, your leg muscles contract when you stand up and stretch when you sit down. Your leg muscles also help you walk.

What is muscle weakness?

Muscle weakness is a common symptom of many diseases and conditions. It is also a common side effect of long-term use of certain medications and of certain physical activities.

Muscle weakness can occur in many parts of the body. For example, muscle weakness can occur in the muscles of your arms and legs.

In the muscles, muscles are made of bundles of muscle fibers. When a muscle contracts, the muscle fibers shorten. This allows the muscle to relax and make room for another muscle to contract.

Muscle weakness can also occur in other parts of the body. For example, weakness of the muscles in your face can make you look old. This is especially noticeable in the muscles of your neck and shoulders.

Muscle weakness caused by diseases or conditions can affect the muscles in your heart, lungs, heart, and muscles that control your bowels and bladder.

Muscle weakness can also be caused by injuries, such as muscle strains, fractures, or muscle tissue tears. These injuries can make movement more difficult.

Sometimes, muscle weakness can be temporary. For example, it can occur after an injury or an operation.

Sometimes, muscle weakness is the result of an inherited condition. For example, it can be caused by an inherited condition, such as spinal muscular atrophy, that affects your muscle cells.

What is muscle atrophy?

Muscle atrophy is the loss of muscle mass, or muscle mass density.

As muscle mass decreases, the size of your muscles decreases. Muscle atrophy can occur in a number of different parts of the body.

For example, when muscle mass decreases in the muscles that control your heart, your heart may not be able to move correctly. This can result in heart failure.

Sometimes, muscle atrophy is the result of a disease or condition. For example, it can occur when a virus or bacteria causes inflammation in the muscles.

Muscle atrophy can also be caused by injuries, such as muscle strains, muscle tears, and fractures.

What causes muscle weakness?

A number of different conditions can cause muscle weakness.

Muscle weakness can be the result of a disease or condition. For example, it can occur with:

  • Muscular dystrophy
  • Muscular dystrophy in children
  • Myasthenia gravis the inflammation of the nerves that causes muscle weakness
  • Amyotrophic lateral sclerosis the nerve damage in the brain that causes muscle weakness
  • Muscular atrophy the loss of muscle mass caused by a disease or aging
  • Muscular dystrophy and muscular dystrophy in children
  • Lambert-Eaton myasthenic syndrome, a rare autoimmune disease that causes muscle weakness
  • Polymyositis the inflammation of the muscles
  • Polymyalgia rheumatica the inflammation of the muscles
  • Thyroiditis the inflammation of the thyroid gland
  • Amyloidosis a disease that causes the build up of proteins in the body
  • Diabetes the inflammation of the pancreas
  • Lyme disease a tick-borne disease that causes the inflammation of the joints and nervous system
  • Cancer cancer that affects the muscles can cause muscle weakness
  • Rheumatoid arthritis the inflammation of the joints and the muscles

Sometimes, muscle weakness is temporary. For example, it can occur after an injury or operation.

Sometimes, muscle weakness is caused by an inherited condition such as spinal muscular atrophy, muscular dystrophy, or muscular dystrophy in children.

How is muscle weakness diagnosed?

In order to diagnose the cause of muscle weakness, your doctor will ask about your medical history, such as any diseases or conditions you have and any symptoms you have. They will also ask about your symptoms and how long you have had them.

Your doctor may refer you to a physical therapist. A physical therapist will help you learn exercises to strengthen and extend the muscles in your arms, legs, and back.

Once you have learned the exercises, your doctor will examine you to see how well you are able to move the muscles. This can help to determine what part of your body is weak.

How is muscle weakness treated?

Treatment will depend on the cause of your muscle weakness and on how severe it is.

Treatment for muscle weakness caused by a disease or condition will depend on the cause of the muscle weakness. In some cases, the cause is an inherited condition.

If your muscle weakness is the result of an inherited condition, your doctor may recommend:

  • Genetic testing to determine if you have the condition. This is often an expensive test.
  • Taking medications to reduce the inflammation in your body.
  • Treating your underlying condition with medications or other treatments.
  • A physical or occupational therapy program that helps strengthen the muscles in your arms, legs, and back.

Common medications used to treat muscle weakness include:

  • Anticonvulsive drugs. These drugs help to control the symptoms of nerve inflammation.

Finally

If your muscle weakness is caused by an injury or other condition, you may need to learn exercises. These can help you strengthen and increase the range of movement in your muscles.

For example, if you have muscle atrophy, a physical therapist can teach you exercises that will help you increase the size of your muscles. These exercises can also help reduce the symptoms of muscle atrophy.

Your doctor can also help you learn exercises to strengthen your muscles. These can help to increase your range of movement and reduce the symptoms of muscle weakness.
