Although the Frank-Starling mechanism can be accounted for in terms of length-tension relationships, one could also invoke increases in cytosolic calcium resulting from opening of stretch-activated calcium channels. What role does calcium play in muscle contraction, and why would increasing cytosolic calcium levels increase the amount of tension developed?
