1) Explain the anatomical breakdown of a muscle.

2) What is excitation-contraction coupling?

3) Explain the sliding filament theory.

4) What happens to a muscle if an action potential stops stimulating a muscle fiber?

Solutions

Expert Solution

  1. Muscle breakdown cause the release of myoglobin to the blood stream. It's a protein, which stores oxygen in muscle cells. Myopic may damage kidney. Rhabdomyolysis is the process of breakdown of damaged skeletal muscle.
  2. Excitation contraction coupling is a process by which an electrical stimuli triggers the release of calcium by sarcoplasmic reticulum initiating the mechanism of muscle contraction by sarcomere shortening
