PPT-Would you expect type 1 or type 2 fibers in heart muscle?

Adjustments to stroke volume What is a heart attack what are short and long term causes of heart attacks Heart disease Myocardial infarction Coronary arteries nourish cardiac cells Blockage due to plaques embolisms vascular spasm. 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.. RYR1. Mutations. DX. CC. MC. IN. CN. Type I Fiber. Predominance. RyR1.
