Description

Papillary muscle from cat heart shows a step-like end-to-end junction of two cardiac muscle cells. The longitudinally oriented lateral cell boundaries are straight and exhibit extensive gap junctions (indicated by stars). Figure 106 from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of the accompanying chapter is available on the ASCB's BioEDUCATE website.
