Studies on human coronary arteries. I. Branch pads or cushions.
The chronology of branch pad development in fetal coronary arteries, their topographic and structural particularities as well as some observations on their evolution in succeeding age-groups are presented. A peculiar emphasis is given to the microarchitecture and functional significance of longitudinal muscle columns as a prevalent structural component of branch pads.
