PPT-More contraction! Review Principles of Muscle Mechanics

Same principles apply to contraction of a single fiber and a whole muscle Contraction produces tension the force exerted on the load or object to be moved Review Principles of Muscle Mechanics Contraction does not always shorten a muscle. 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.

Review Principles of Muscle Mechanics. Same principles apply to contraction of a single fiber and a whole muscle. Contraction produces tension, the force exerted on the load or object to be moved. Foldable. You will make a Foldable to illustrate the steps in skeletal muscle contraction (use figure 10-1 on pg. 299). You may use any type of foldable (but only 1 colored sheet of paper). You may combine steps so you have less than the 10 steps on pg. 299. Skeletal & Cardiac excitation . & contraction. Mike Clark, M.D.. NOTE.
