RIGHT PAPILLARY MUSCLES - MACROSCOPIC ISSUES (Abstract): Papillary muscles are muscular columns present in the ventricular wall, attached with one end on the wall and with the other through the cordae tendinae inserted on the parietal surfaces of the atrio ventricular cusps. For macroscopic and mesoscopic anatomical investigation, through dissection method, of the septal arteries and papillary muscles, we used 14 specimens. These were prelevated from human adult bodies, mostly formolised, by different age and gender, without any coronary pathology. There are two main models for supplying of anterior 2/3 of the interventricular septum: one determined by the presence and morphological definitionof the anterior descending septal artery, which we met in 6 of the 14 specimens dissected (46.15%).
