NettetSkeletal Muscle Fiber Structure. Each skeletal muscle fiber is a skeletal muscle cell. These cells are incredibly large, with diameters of up to 100 µm and lengths of up to 30 cm. The plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma is the site of action potential conduction, which triggers muscle contraction.

NettetThe light-staining bands are called isotropic or I-band because polarized light is reflected equally when passed through it. Dark lines termed Z-lines or Z-disc bisects the I-bands. The center of each A-band contains a paler region called H-zones or H-band. NettetEach sarcomere divides into different lines, bands, and zone: “I” and “A” bands, “M” and “Z” lines, and the “H” zone. – Z-lines define the boundaries of each sarcomere. – The M-line runs down the center of the sarcomere, through the middle of the myosin filaments. – The I-band is the region containing only thin filaments. rmurk rathnayaka google scholarNettetThe M-line (Mittelschiebe) bisects each A-band (and, in doing so, bisects each H-band).
