14.4 Cardiac musculature



Histological aspects


In contrast to the myoblasts of the skeletal musculature, the myocardial precursor cells do not fuse into a syncytium but rather remain as individual cells. They are connected with one another, though, by complex adhering junctions, the intercalated disks, and thus form a cellular bond that stays together.
