The bronchial arteries, which provide the nutrient supply to the lung, have been studied in the normal gross anatomy and the pathology as well. The present study was made to compare the Korean results of the morphology investigated by us with the results obtained by others.
114 Korean cadavers of both sexes consisting of 52 males and 62 females, which were arranged for dissection of the gross anatomy at Yonsei University College of Medicine, were used. The authers have selected the specimens carefully to eliminate any unsuitable dissections performed for this study.
In the types of both bronchial arteries by number, the Type 2, which was one bronchial artery to each lung, was observed in 57 out of 114 cases (about 49.99% in the incidence) and the Type 2 showed the most frequent incidence in the Types of right and left bronchial arteries by number.
A right bronchial artery frequently arised in common with an aortic posterior intercostal artery. One right bronchial artery arised in common with an aortic. posterior intercostal artery was found in 61 out of 114 cases (about 53.5% in the incidence). The occurrence of one right bronchial artery arised from the 1st aortic posterior intercostal artery was 50 out of 61 cases (about 81.96% In the incidence).
In the mode of origins of bronchial arteries in each body, all bronchial arteries arised indepentently from the aorta or its branches, were found in 66 of 114 cases (about 57.86%). In the rest of 48 cases, 2 or more bronchial arteries arised from common stems.
In the left sides of 114 cases 155 bronchial arteries were found by the authors. Among them 143 bronchial arteries arised from the thoracic aorta and its tributaries (about 92-26% in the incidence) and 12 bronchial arteries arised from the aortic arch (about 7. 74% in the incidence).
In the right sides of 114 cases 150 bronchial arteries were observed. 79 out of 150 bronchial arteries arised from the stun of the thoracic aorta (about 52.66°´ in the incidence) and 9 bronchial arteries arised from the aortic arch (about 6.0% in the incidence). From the first aortic posterior intercostal arteries of the right sides 5.2 bronchial arteries arised (about 34.66% in the incidence, which were
