摘要: A great diversity of forms multicellular organisms having come into being during animal evolution has determined the exclusively structural and functional variety their muscles differing, particularly, in mode activation. In vertebrate twitch a crucial step excitation- contraction (E-C) coupling concerns mechanisms whereby electrical activity T-tubular membrane (TTM) induces release Ca2+ from sarcoplasmic reticulum (SR). The investigation this key question E-C resulted two principal hypotheses about nature T-SR signal transmission: (i) SR triggered by change tubular polarization (ii) induced specific chemical transmitter T-system.
