PDF-Contraction Action

Songs Poems and Rhymes Developed by Cherry Carl Artwork. 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.. ANSC 3404.
