How are smooth muscles organised
WebSmooth muscle cells have lots of different functions and so the cells are organised into two groups. These are catagorized as: multi-unit smooth muscles or single-unit smooth muscles. The majority of smooth muscle is of the single-unit type for simultaneous contraction within organs. WebSimilar to cardiac muscle, smooth muscle is not under voluntary control. In addition to spontaneous stimulation, smooth muscle can be stimulated by pacesetter cells that are similar to pacemaker cells and trigger waves of action potentials in smooth muscle. Smooth muscle can also be stimulated by the autonomic nervous system or hormones.

Muscular … WebSmooth 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.
