A variety of smooth muscle relaxants can promote the occurrence of "Ca++ sparks" beneath sarcolemma of smooth muscle
The Ca++ sparks are thought to originate from a local activation of the ryanodine receptor, just beneath the sarcolemma. These Ca++ sparks promote relaxation by: A. activating the Na+-Ca++ antiporter in the smooth muscle B. activating the Ca++-dependent phosphatase calcineurin in the smooth muscle C. activating Ca++-dependent K+ channels in the smooth muscle D. promoting myosin light chain phosphorylation smooth muscle E. activating Rho kinase in the smooth muscle
