Three-Dimensional Structure of Muscle Membranes Involved in the Regulation of Contraction in Skeletal-Muscle Fibers

  • Lee D. Peachey

Abstract

One area in cell biology in which considerable advance has been made over the last 25 years is the study of how internal membranes in skeletal-muscle cells [specifically the transverse tubular system (T-system) and sarcoplasmic reticulum (SR)] are involved in the control of the contractile state of the cell. This chapter will review this research and summarize the present state of our understanding in this area (for a broader review of muscle-cell biology over the last 25 years, see Franzini-Armstrong and Peachey, 1982). As will be seen, we now have a quite complete understanding of how the T-system of a variety of types of skeletal-muscle fibers is constructed and how it works. Furthermore, this knowledge from muscle cells, in which contractile and control mechanisms are highly elaborated and relatively easy to study, should turn out to be useful in studies of nonmuscle cells, where one might perhaps expect to find similar, though probably simpler, control systems.
