Here I contrast the skeletal and cardiac muscle in terms of the control muscle growth and of sarcomere component synthesis. The differences are major and reflect the long term needs of the two systems. With the skeletal system there is growth of both the number of myocytes and the sarcomere components within them dependent on demand made of the muscle. Unlike skeletal muscles the normal adult heart is greatly restricted in size, number of myocytes and their content of contractile proteins, i.e. there is little change on demand. Over time proteins get damaged or decay and for the normal heart this implies a strictly controlled maintenance synthesis of sarcomere components. From the studies of abnormal, mutated systems there is one thing inherent to and more pronounced in cardiac muscle, the FrankStarling Law of the Heart derived from the angiotensin ii type 1 receptor that my studies indicate is central to the control of sarcomere component synthesis.
