a few muscle fibers innervated in each group impulse spreads through gap junction and contracts as a unit often autorhythmic multiunit: cells or groups of cells act as independent units arrector pili of skin and iris of eye * smooth muscle cell smooth muscle contraction: mechanism smooth muscle relaxation: mechanism comparison of role of calcium in bringing about contraction in smooth muscle and skeletal muscle * contraction-relaxation – myosin based regulation ca2+ ca2+ calmodulin mlck relaxation contraction mlcp mlck, myosin light chain kinase mlcp, myosin light chain phosphatase important points: initiated by calcium calcium binds to calmodulin (instead of troponin as in skm) ca-calmodulin-mlck complex leads to phosphorylation of mlc (requires 1 atp) mlc is part of myosin head phosphorylated myosin head binds to actin and power stroke occurs automatically a second atp is required to release myosin head from actin cross-bridge cycling requires both mlck and mlcp mlc active …
