3.11 Cardiac muscle

Version française

Section of a human cardiac muscle next to its endocardial surface (End).

This field shows, in cross or oblique sections, a collection of large cardiocytes (+). Standard-sized cardiocytes are seen at the top of the field (*). The large cardiocytes below have a large pale central cytoplasm, a few showing a nucleus (N). The acidophilic myofibrils occupy the periphery of the cells.

These large cardiocytes belong to an atrioventricular bundle considered to be part of the conducting system of the heart controlling the sequential rhythmicity of the atria and ventricles.

Some intensely stained dense connective tissue (C) is also indicated

Stain: H–E
Magnification: ×500
