In this case both arytenoids can be seen protruding into the lumen of the larynx at each inspiration; at each expiration they are forced flutteringly aside. The paralysis can be complete or incomplete, and is often better developed on one side than on the other. VIII, Percussion of the Thorax. To properly percuss the lungs a knowledge of their topographical position is essential. Anatomy. The lungs and heart do not occupy the whole of the thoracic space. The abdominal viscera encroach upon a greater part of it. The partition between the chest and abdominal organs is the diaphragm..... Heart;--.--Line of Insertion of Diaphragm;--Boundary of Lung during Expiration. This organ is inserted, in the arc of a circle, to the inner surface of the whole thorax, reaching in an oblique direction from the sternum backwardly and upwardly to the lumbar vertebrae. In the region of the sternum its points of attachment are at the union of the ribs to their cartilages, farther posteriorly, however, the diaphragm does not extend down as far as the cartilages of the false ribs, but passes obliquely across their inner surfaces until, finally, at the last rib it finds attachment at the superior end. The diaphragm arches forward from its points of insertion, extending into the thoracic cavity in the shape of a cone the apex of which reaches in the various animals, somewhat beyond the middle of the 7th or 8th rib. At expiration the diaphragm lies with its muscular portion directly against the lateral chest wall, the tendinous portion then forming the partition. With the beginning contraction of the diaphragm at inspiration the arch becomes ...
