Skeletal Muscle Microscopy
Skeletal muscle consists of muscle fibers (cells) which are multinucleated and packed with cylindrical bundles called myofibrils. These myofibrils are composed of repeating units called sarcomeres, the functional contractile units, formed by the organized arrangement of thick filaments (myosin) and thin filaments (actin). This arrangement creates a striated or striped appearance under the microscope.
