What Is the Role of Calcium in Muscle Contractions?

Answer

The role of calcium in muscle contractions is that it simply acts as the trigger for a muscle to contract. Basically, calcium ions help start the action potential to signal muscles fibers to enter a state of contraction and start depolarization for to accomplish a 'power stroke' (muscle contraction).
