Question

Quizplus · Accepted Answer

Intercalated discs allow electrical impulses to be transmitted rapidly from cardiac fiber to cardiac fiber because the network of fibers is connected at these discs.
Myosins are filaments that are a part of cardiac tissue.They do not play a role in conduction.
Troponin Ts are involved in contraction,but are not part of the sarcolemma.
I bands are a part of the filaments bud,which do not conduct impulses in a cell-to-cell fashion.
