Muscular system

One of the most important parts of the human body are undoubtedly muscles. It is a muscular system which is of great importance when walking and in the overall motion. Muscular system consists of three basic groups of muscles. Each muscle group is specific, otherwise the controls and operates on a different kind of movement.

Muscular system using bones and tendons form a movement and supporting system of the human body. Without this system, we could not move and would not hold together.

Active movement of the muscle system does not focus only on the overall human movement, but also to individual organs and parts. Science, which examines the muscles called myology.

lean body

  • Beginning – where the muscle begins
  • Upon – where the muscle ends, where the clamps
  • Muscle belly – the largest and most powerful muscle instead
  • Tendon – ligaments, which helps muscle clamping
  • Fascia – the fascia muscle, protecting muscle

muscle function

The basic properties of each muscle contraction is a possibility, or contraction. Muscle acts on the basis of special muscle cells myofibrils. They are composed of two basic molecules actin and myosin. Muscle contraction is a result of complex chemical reactions. Muscles for active movement need large amounts of energy, in this case glucose, which is fed into the muscle with blood.

Functional classification of muscles

  • The main muscles
  • auxiliary muscles
  • fixation muscles
  • neutralizing muscles

Muscles in numbers

The number of muscles in the human body is around 600, even though it is one of the least numerous human systems. Muscles up to 40% of the total weight of our body. During the life of muscle mass may fluctuate and you may consciously adjustments, such as exercise, proper diet and weight training.

Pathology of the muscular system

  • Muscle cramps – occurs when there is insufficient oxygenation and nutrients in the muscle.
  • Muscle atrophy – muscle weakness and muscle mass.
  • Muscle Armor – inadequate supply of oxygen to the muscle.
  • Inflammation and irritation of muscles – occurs when excessive strain on the muscles.
  • Tearing a muscle – caused the accident.


Muscle system is divided into three basic groups that have different functions and different location. Muscle groups are very different.

  • Striated muscle skeletal – will operate
  • Striated muscle heart – unruly wills
  • Smooth muscle – unruly wills

Individual muscle groups have described in separate articles.

muscle fascia

The muscle fascia or fascia is present in all the muscles of the human body. It is a fibrous casing individual muscle or whole muscle groups.Fascias are important for active movement of muscles and protects the muscle from injury and the inflammatory process.


Very strong fibrous ligament that connects the bone and muscle. This is a very important part of the support system that binds together the bone and muscle. Tendons have almost no vascular supply or nerve endings. Among the most famous tendon disease include tennis elbow, there is a tendinitis in the elbow. In case of any damage to tendon movement is completely closed, for example by incision of the Achilles tendon formed impossibility walk.
