Jelly formed around the hea tube during early development, contributes to the formation of:
C i.e. Myocardium Dorsal mesocardium forms transverse pericardial sinusQ; somatopleuric mesoderm forms parietal pericardiumQ; splanchnopluric mesoderm forms myocardium & conduction system of heas (i.e. Purkinje fibers) Q; neural creast cells form subpulmonary infundibulumQ.Cardiac jelly forms endocardial cushion and myocardiumQ
