-There are two main parts of the striation pattern of skeletal muscle fibers: * The light bands (I bands) are made up of tink filaments of actin attached to Z lines.*The dark bands (A bands) are made up of thick filaments of myosin that overlap thin filaments of actin.There are two main parts of the striation pattern of skeletal muscle fibers: * The light bands (I bands) are made up of tink filaments of actin attached to Z lines.
A skeletal muscle is composed of a variety of tissues, including layers of connective tissue. Fascia covers the surface of the muscle, epimysium lies beneath the fascia, and perimysium extends into the structure of the muscle where it separates muscle cells into fascicles. Endomysium separates individual muscle fibers.uscle fibers within the fascicle are surrounded by endomysium (320x). connective tissue, therefore, enclose and separate all parts of a skeletal muscle. This arrangement allows the parts to move somewhat independently. Also, many blood vessels and nerves pass through these layers.
