A muscle also can stop contracting when it runs out of ATP and becomes fatigued (Figure 9.4. 2 ). Figure 9.4. 2: Relaxation of a Muscle Fiber. Ca ++ ions are pumped back into the SR, which causes the tropomyosin to reshield the myosin binding sites on actin strands.

WebbSkeletal or Striated Muscle Skeletal muscle tissue is distinctive due to its long, tube-shaped multinucleated fibers (cells) with visible cross-striations. The striations are the result of highly ordered actin and myosin filaments within sarcomeres , the basic contractile units of muscle fibers (see images below). WebbFunctional morphology of muscles.
