Webb9 okt. 2024 · Smooth muscles have more elastic properties than striated muscles, and they can relax and tense at the same time. vascular smooth muscle cells contribute to the stability and development of the vascular system. They are thought to be involved in the location and presentation of vascular diseases. Webb7 okt. 2024 · Smooth muscle relaxation occurs when a substance directly stimulates the contraction mechanism, as in the second case. It is critical to decrease intracellular Ca2+ concentration and increase MLC activity in order to complete the relaxation process. As a result, smooth muscle relaxation may play a role in increasing blood flow during exercise.

WebbSmooth muscle contraction, induced by acetylcholine through the muscarinic M3 receptor, starts with the release of Ca2+ from intracellular stores. Ca 2+ binds calmodulin that is complexed with myosin light chain kinase. This leads to activation of the kinase and subsequent phosphorylation of regulatory myosin light-chain at serine-19. Webb6 juli 2015 · Excessive migration and proliferation of smooth muscle cells (SMCs) has been observed as a major factor contributing to the development of in-stent restenosis after coronary stenting.
