Costomediastinal recess-the costomediastinal recess is an area right next to the cardiac notch, which is an indentation in the superior lobe of the left lung. if you take a very deep breath, the lingula of the left lung, which is formed by the cardiac notch, will tend to expand into the costomediastinal recess. the costodiaphragmatic recess is the lowest extent of the pleural cavity or sac. it is the part of the pleural sac where the costal pleura changes into the diaphragmatic pleura. the cupola is the part of the pleural cavity which extends above the level of the 1st rib into the root of the neck. the hilum is found on the medial surface of the lung-it is the point at which the structures forming the root enter and leave the lung. the pulmonary ligament is a fold of pleura located below the root of the lung, where the visceral pleura and the mediastinal parietal pleura are continuous with each other.
