and states that “the energy of contraction” of cardiac muscle “is a function of the length of the muscle fibre.” In fact, the longer the fibres at the beginning of systole, the stronger is ...

Heart Rate Increase in rate of contraction of cardiac muscle - cardiac output increases Decrease in rate of contraction of cardiac muscle - cardiac output decreases Breathing Rate Smooth muscle of ...

Contractile proteins are proteins that mediate sliding of contractile fibres (contraction) of a cell’s cytoskeleton, and of cardiac and skeletal muscle. Heart and muscle contractile fibres ...
