Coronary

CORONARY (coronalis, coronarius, coronoideus, from the Latin corona—wreath, crown), an anatomical term designating: 1) the arteries branching from the bulbus aortae that supply the myocardium, encircling the heart like a wreath (aa. coronariae cordis dextra et sinistra); 2) the branches of the external maxillary artery, which form a vascular ring around the oral opening within the thickness of the lips together with their counterparts (aa. coronariae labii superioris et inferioris); 3) the coronary sinus of the heart (sinus coronarius cordis), the main collector of the cardiac veins, opening into the right atrium; 4) sulcus coronarius cordis—the coronary sulcus of the heart, in which the cardiac vessels lie; 5) ligamentum coronarium hepatis, the coronary ligament of the liver, which passes as a duplication of the peritoneal fold from its posterior border to the postero-superior wall of the abdominal cavity and represents part of the supporting apparatus of the liver; 6) sutura coronalis—the coronal suture between the squamous part of the frontal bone and the parietal bones; 7) processus coronoideus mandibulae and ulnae (Heister's term)—the coronoid process of the mandible and of the ulna, which, however, according to Hyrtl (Onomatologia anatom., Wien, 1880), more closely resemble the hook at the end of an ancient Greek bow (corone).
