Your fast-twitch and slow-twitch muscle fibers are separated into three distinct types.Slow-twitch fibers contain type 1 muscle fibers, while your fast twitch fibers contain both type 2a and type 2b.The percentage of each muscle fiber differs among everyone, and from one muscle to another in the same individuals, according to Fitness: The Complete Guide, by International Sports Sciences Association.hoto Credit Digital Vision./Photodisc/Getty Images.

Muscle fibres are cylindrical, and multinucleated. Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber. The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers called fascicles. All muscles also contain connective tissue arranged in layers of fasciae.
