Lateral curvature of the spine and round shoulders . ly convex and directed forward and downward, isformed by the sternum and the costal cartilages. The plane of thesuperior opening or inlet of the thorax is inclined forward anddownward, showing a greater obliquity in women than in inferior border of the thoracic cage is formed by the twelfththoracic vertebra, the lower borders of the twelfth rib, and by twocurved lines, extending from the anterior extremities of the last ribto the inferior angles of the gladiolus, touching the anterior extremi-ties of the eleventh rib and the costal cartilages of the tenth, ninth,and eighth ribs. The angle formed by these lines is known asthe subcostal angle. The inferior surface of the thorax is directedforward and downward. i6 ANATOMY OF VERTEBRAL COLUMN AND THORAX MUSCLES OF THE SPINE AND THORAX The general grouping and arrangement of the muscles in theirrelation to the spine has an important practical bearing on spine lies toward the back of a more or less cylindrical muscular.
