How does smooth muscle relax?
Smooth muscle relaxation occurs either as a result of removal of the contractile stimulus or by the direct action of a substance that stimulates inhibition of the contractile mechanism . Regardless, the process of relaxation requires a decreased intracellular Ca 2 + concentration and increased MLC phosphatase activity.
Can smooth muscle grow?
The increase in smooth muscle mass may be due to hypertrophy (an increase in cell size), hyperplasia (an increase of cell number), or an increase in extracellular matrix. Hypertrophy of smooth muscle cells and increase in extracellular matrix are reportedly responsible for hypertrophic pyloric muscle in IHPS ( 7 – 9 ) .
