Fibers and Seketal Muscles

Each skeletal muscle consists of a bundle of myofibrils. Muscle fibers are composed of units called Sarcomeres. The sarcomas are a series of elongated filaments that overlap for a long time. When Sachsmere encounters its adjacent sarcomere, it is called the "z-line". The sarcomere repeat unit explains the unique band pattern seen in the striated muscle. The thick line of the sarcomere constitutes "A band". This is the center of sarcomere. These thick filaments consist of myosin.

Human skeletal muscle consists of nonuniform gathering of muscle fiber type 1-3 This type of muscle fiber can make human muscle demonstrate various abilities. In addition, muscle fibers can be adapted to changing needs by varying the size or composition of the fiber type. This plasticity is the physiological basis of many physical therapy interventions aimed at increasing the patient's physical strength development or endurance. Changes in the composition of the fiber type may also be due to some of the injuries and injuries caused by prolonged inactivity, limb fixation, or muscle innervation removal 2. It leads to several classification systems. The purpose of this update is to provide the basic knowledge necessary to read and explain human skeletal muscle research.

Muscle fiber types can be described using histochemical, biochemical, morphological, or physiological characteristics, but classification of muscle fibers by various methods is not always consistent. Thus, muscle fibers that can be combined with muscle fibers by classification techniques can be placed in different categories using different classification techniques. In order to understand muscle fiber classification technology, basic understanding of muscle structure and physiological function is necessary.
