Book excerpt: Excerpt from Morris's Human Anatomy, Vol. 5 of 5: A Complete Systematic Treatise by English and American Authors; Surgical and Topographical Anatomy Outline of the heart. Its relation to the chest-wall. - The upper limit of the heart (base) will be defined by a line crossing the sternum a little above the upper border of the third costal cartilage, reaching about 1 2 cm. (9 m.) to the right and about 2 5 cm. (1 m.) to the left. Its apex corresponds to a point in the fifth space, 3 7 cm. (it in.) below the male left nipple, and 2 5 cm. (1 in.) to the 1nner side. This point will be at 7 5 cm. (3 1n. From the left border of the sternum. The right border (right atrium) will be given by a line, slightly convex outwards, drawn from the right extremity of the upper border to the right seventh chondro-sternal joint. If another line, similarly slightly convex, be drawn onwards from this point across the last piece of the sternum, just above the xiphoid cartilage, to the apex, it will give the lower border (marge acutus of right ventricle), which rests on the central tendon of the diaphragm. The left border (margo obtusus of left ventricle) will be given by a line, convex to the left, passing from the left extremity of the upper border to the apex, well inside the nipple-line. This line should be 75 cm. (3 in.) from the middle of the sternum at the level of the fourth costal cartilage. The base of the heart is o posits the four middle thoracic vertebrae, viz., the sixth, seventh, eighth, and ninth. The apex and anterior or costo-sternal surface have been mentioned. The posterior or diaphragmatic surface (chiefly left atrium and left ventricle) rests upon the diaphragm, mainly the central tendon, to which the intervening pericardium is connected, and is thus adjacent to the liver and a small portion of the stomach. If a circle 5 cm. (2 in.) in diameter be described around a point midway between the left nipple and the lower end of the gladiolus, it will define with sufficient accu racy for practical purposes that part of the heart which lies immediately behind the chest wall, and which 18 uncovered by lung or pleura.
