Inferior lobe-because of the sharp angle of the oblique fissures, the posterior surfaces of both the right and left lungs are almost entirely comprised of the inferior lobes. and remember-the middle lobe of the right lung is not part of the posterior surface of the lung. so, a stab wound halfway between the apex and diaphragmatic surface of the right lung would result in injury to the inferior lobe. the cardiac notch is an indentation on the left lung which helps to form the lingula. the lingula is part of the superior lobe of the left lung, which forms the anterior and superior sides of that lung. the superior lobe (along with the middle lobe) forms the anterior surface of the right lung. the superior lobe also forms the superior aspect of both lungs.
