Observations on the cellular structure of the dog heart as seen in the electron microscope are described. Electronmicrographs illustrate the ultrastructure of the dog myocardial cell, especially the relationships of the intercalated disc and the sarcolemma to form the cell boundaries and the relationships of the myofibrils and “Z” bands to the sarcolemma which result in an “accordion-like” appearance of the cell after contraction.
