[SeC. 1. axilla or at the base behind—that is, as far as possible away from the air tubes— the breathing sounds are entirely different from those heard in the other places specified. The breathing sounds heard in these various- parts have since Laennec's tune been called laryngeal, tracheal, bronchial, and vesicular respectively. Pathologically, these terms become of significance when they are heard in places m the chest where they should not normally be heard at all. If, in places where vesicular breathing ought normally to be heard, vesicular breathing disappears, and m its stead some other kind of breathing is heard, the conclusion DIAGRAMMATIC REPRESENTATION OF THE Tt^l^:^^^^ BREATH-SOUNDS. dealt with later, that that portion of the lung is in a condition of disease; and, the more abnormal the breathing is, the greater the pathological changes which have taken place. This is the real reason why so much im- portance is attached to these terms, for they are regarded as the measure of the pathological intermediate change. Over the larynx, iu- (? Bronchiolar) All called by some spiration is heard as well ^ teachers ^s expiration ; both are Bronchial ^oi^y as it were, and both have a peculiar (By others Tubular) character, such as might be produced in a large hollow space as we know the larynx to be. On account of this hollow character this kind of breathing when heard elsewhere is often called, not laryngeal, but am- phoric or cavernous. Over the trachea, in- spiration and expiration are both heard. The sounds are still loud and noisy ; though not quite so loud as over the larynx, they are somewhat raised in tone, and have lost some of their hollow character. Over the positions described where bronchial breathing may be heard, both sounds are still audible, but with a still higher pitch and a much harsher character. When, in disease, instead of vesicular l3reathing other sounds are heard, they are called lary7igeal, tracheal, or hronchial, according as they approach most nearly to the characters of the breath sounds heard in these respective places. 1 Beonchial Tracheal Laryngeal Amphoric Cavernous
