All the internal organs of the body whatever, have their own outer ligaments or bindings. Obviously, these provide for communication not only with the inner parts, even the very smallest, but also with those outside, especially those which function conjointly. The bindings for the internal organs in the body, such as the peritoneum, the pleura, the diaphragm, the mediastinum, the pericardium-all represent general principles. But [to describe] these connective parts and the respective communications and responses they provide for, would be a very large task.
