Question

For Aaron's biceps muscle to be able to generate the same amount of tension as before the accident, the muscle fibers that were not damaged would need to generate more tension to make up for the fibers that were damaged. Explain how these healthy muscle fibers would do this. Would the Ca2+ concentration in the cytoplasm in the healthy muscle fibers need to increase or decrease to generate a stronger contraction? How does this happen?

Answer 1

Biceps muscles are different layered muscles of the arm which is the largest muscle and lies in the front of the upper arm between the Elbow and Shoulder. These are the muscles which help to control the motion of different joint shoulder as well as elbows. This leads to providing the essential movement and function to the forearm in lifting.

For the biceps muscle of the patient that is able to generate a small amount of function as before the accident the fiber of muscles was not damaged to generate more tension. The healthy muscle fibers can perform the ability of movement by creating energy and fuel to muscle activity with oxygen. Type of muscle fibers can form the oxidative and glycolytic metabolism to form more power contraction to decrease the fatigue. The calcium Ion concentration is increased due to the release of the cytoplasmic iron concentration. Cells of muscle contraction are based on enhancing the cytosolic calcium concentration. The calcium-binding with troponin that changes the shape and removes the proper myosin binding site. Electrical depolarization of the cell membrane is likely to open the calcium channels that cause the intracellular concentration of calcium to bind with the protein known as calmodulin.
