Abstract
Smooth muscles have traditionally been classified as phasic or tonic, the tonic muscles being those which maintain a steady tension indefinitely with a low consumption of energy. Until ten years ago it was considered that the differences between smooth muscle types reflected different innervation or excitation-contraction coupling. However, recent work makes it clear that the contractile apparatus itself is adapted in tonic muscles.Mesh:
