<prompt> True statement about smooth musclesPresence of CaveolaeCa2 binds to troponin CThe anchorage for actin filaments is given by Z-linesVoltage gates L-type Ca2 channel are present in T-tubules  <response>: Smooth muscleNo T tubules. Instead it has Caveolae which is invagination of smooth muscle membrane, it has voltage gates L-type Ca2 channelNo troponin Ca2 binds CalmodulinNo Z lines. Achorage for actin filaments is provided by dense bodies.
