-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.
Each skeletal muscle fiber is a single cylindrical muscle cell. An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium.Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.n individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering.
