Operative surgery, for students and practitioners . in between the lobes and intimately united with itssurface; after thus entirely enveloping the lung it reaches the ante-rior aspect of the root of the lung, whence it is reflected forwardtoward the sternum as the anterior portion of the mediastinal pleura;upon reaching the posterior surface of the sternum it becomes con-tinuous with that part of the parietal pleura which lines the innersurface of the wall of the chest: the pleura sterno-costalis. Aboveand below the level of the root of the lung the mediastinal pleurapasses all the way as an uninterrupted layer from behind forward,from either side of the spinal column to the posterior surface of thesternum. Limits of the Pleura as Indicated by Lines upon the Chest Anterioe Edge of the Pleura.—The line which indicatesthe anterior edge of the right pleural sac commences, above, behindthe right sterno-clavicular articulation; from this point it passesdownward and inward behind the sternum, and at the junction of THE PLEURA. 295. Fig. 146.—Outline of Pleura, etc. Front view. A, apex of lung and domeof pleura; D, line of diaphragm; U, outline of heart; L, solid lines show theedges of the lungs; P, dotted lines correspond to the edges of the pleura. 296 THORAX. the manubrmm with the body of the sternum it lies close to themiddle line; it is then continued downward behind the middle ofthe body of the sternum, and opposite the articulation of the fourthcostal cartilage it curves outward, as it descends, to reach a pointcorresponding to the lower border of the sternal end of the sixthcostal cartilage, whence it may be traced farther downward andbackward as the lower edge of the pleura. The line whkh marks the anterior edge of the left pleural sacis somewhat different. It commences above, behind the left sterno-clavicular articulation, from which point it curves downward andinward toward the middle line and may then be traced downwardbehind the body of the sternu
