Diseases of the chest and the principles of physical diagnosis . Fig. 25.—The^emphysematous chest.(Compare Fig. 33.) Fig. 26.—The chest in scoliosis.(Compare Fig. 17.) IXSPECTIOX 35 of the costo-chondral junctions (rachitic rosary), (2) a transverse fur-row corresponding to the attachment of the diaphragm (Harrisonsgroove), (3) prominence of the sternum (pigeon breast), (4) a longitudinalgroove parallel to the sternum extending to the costal margin. During infancy respiration is mainly abdominal, because the thoraxis^already cylindrical and admits of but httle further outward negative intrathoracic pressure occasioned by the descent of thediaphragm exerts its effects mainly on the lower rilDS. The atmosphericpressure causes the most j-ielding portion of the thorax to cave in (costo-chondral articulations) and thus a depressed groove, parallel to the. Fig. 27. ->sorinal chest with excellent conformation and muscular area above the left nipple is the result of a recent blister. The sternum is formed. Such deformities maj^ result from normal breathing,but are much enhanced in case of inspirator} dj^spnea. Forced inspira-tion, which overexpands the upper chest, causes a forward protrusion ofthe sternum which results in pigeon breast (Fig. 29). This may beunequal in degree on the two sides as the result of scoliosis. The chestis usually shortened, and the costal angle acute. OccasionaUy theremay be a depression of the sternum extending from the middle of thegladiolus to the ensiform cartilage (funnel breast, trichter briist, pectusexcavatum), (Figs. 28 and 30). Although this deformity is usually con-genital, it maj be occupational (schuster brust, cobblers breast) due 36 THE EXAMINATION OF THE LUNGS
