Fast or Slow?. Skeletal muscles contain two main types of fibers, which differ in the primary mechanisms they use to produce ATP, the type of motor neuron innervation, and the type of myosin heavy chain expressed. The proportions of each type of fiber varies from muscle to muscle, from animal to animal, and from person to person.. Skeletal Muscle. Human body contains over 400 skeletal muscles. 40-50% of total body weight. Functions of skeletal muscle. Force production for locomotion and breathing. Force production for postural support. Skeletal – striated & voluntary. Smooth – involuntary. Cardiac - heart. The word “striated” means striped. Skeletal muscle appears striped under a microscope. . Muscles and Muscle Fiber.
