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?

Expert Solution

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.
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

Skeletal A) In skeletal muscle what do we mean by excitation-contraction coupling? B) What causes the excitation? Be specific as to the events and ions and channels involved. C) How is it linked to the contraction events? What ion is involved and how does it work to initiate contraction? (include the proteins activated) D) What causes relaxation? (you do not have to describe the complete contraction event, just what allows it to start and what ends it)
