Structure [edit]. The diaphragm is a dome-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. The dome curves upwards. The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity. As a dome, the diaphragm has peripheral attachments to structures that make up the abdominal and chest walls.
The ârhomboidâ is actually two muscles, the rhomboid minor and the rhomboid major. The rhomboids connect your thoracic spine to your shoulder blades. The rhomboids function is to pull the shoulder blade (and with it, your shoulder/arm) back and inwards toward the midline of your body, toward your spine.
