Coronary Irrigation in Puma concolor (Carnivora: Felidae)

This study described the anatomy of the coronary arteries and their main branches in Puma concolor. The hearts of six individuals of Puma concolor, were analyzed. The A. coronaria sinistra formed the ramus interventricularis paraconalis and the ramus circunflexus. A ramus septal was formed close to...
