The fundamental contractile cell of the heart is the cardiomyocyte. Specialized CMs form the cardiac conduction system, a collection of nodes and cells which initiate and co-ordinate the rhythmic beating of the heart. A contractile cardiomyocyte in the adult human heart is cylindrical in shape and about 100 μm long and 10–25 μm in diameter.In this instance, the cell that I’m referring to is a nerve cell. 3.

A lumen is the inside space of a tubular structure, for example, the inside space of an artery or intestine. Diad. Within the muscle tissue of animals and humans, contraction and relaxation of the muscle cells ( myocytes) is a highly regulated and rhythmic process. In cardiomyocytes, or cardiac muscle cells, muscular contraction takes place due to movement at a structure referred to as the diad, sometimes spelled "dyad."Cardiac hypertrophy is a major risk factor for heart failure, and it has been shown that this increase in size occurs at the level of the cardiac myocyte.
