Diseases of the chest and the principles of physical diagnosis . Fig. 19.—Transversesection of an infants shape is Fig. 20. -An adults chest, elliptical inshape. thoracic development is absolutely determined as regards its ultimateform by the rapidity of growth and time of calcification of the first rib. The length of the normal first rib: Male Female According to Freund is cm. cm. According to Hart is cm. 3. 02 cm. In flat-chested (phthisical) individuals it measures from 3 down to cm. Thismakes the upper chest much narrower and since the rib is also more sloping, makes thewhole antero-posterior thoracic diameter small. The first costo-sternal articulationis frequently ossified. In thoraces having this conformation the pulmonary apicesare more slender and respiratively less mobile. It is to these factors that the pre-disposition to tuberculosis is supposed to be in part due. Pathologic deformities of the chest may be classified among the fol-lowing types: I. The Rachitic Chest.—The rickety (rachitic) chest (due to unduly softbones during its development) is typically characteriz
