Webb1 maj 2000 · During the development of the heart, cardiac myocytes are round shaped cells that differentiate into a rod-shaped phenotype. During the different stages of commitment and morphogenesis, the myocyte organizes its internal structure by undergoing myofibrillogenesis. WebbContracting myocytes are highly variable in size and generally resemble elliptical cylinders in shape. Although their arrangement within the ventricular wall is rather complex, their length runs in a tangential manner, and their transverse axis runs transmurally.
