Please write at least 400 words for the following question.Please describe how you bend your arm, starting with action potentials and ending with the contraction of a muscle. Drugs are often used to relax muscles during surgery. Which of the following chemicals do you think would make the best muscle relaxant and why? Chemical A: Blocks acetylcholine receptors on muscle cells, Chemical B: Floods the cytoplasm of muscle cells with calcium ions. The greatest concentration of thoroughbred horse farms is in the bluegrass region of Kentucky. The grass in the limestone-based soil of this area is especially rich in calcium. How does this grass affect the development of championship horses? When a person dies, muscles become rigid and fixed in position, a condition known as rigor mortis. What is going on to cause this? Please explain, in terms of the molecular mechanism of contraction, why muscles become rigid, rather than limp, soon after death.
