Comparative Anatomical Studies on Coronary Arteries of Various Species

The present study was conducted on coronary arteries of buffalo, horse, camel and dog. In camel the left coronary artery and its circumflex branch were well developed. The intermediate groove was also well developed and was occupied by branch of left coronary artery. In horse, intermediate groove was absent. The circumflex branch of left coronary artery was anastomosed with right circumflex branch. In dog and horse, the descending branches of right and left coronary arteries were not anastomosed, whereas in buffalo and camel these branches were joined with each other.
