Now we're nearly ready to move on, to look at the blood vessels and nerves of the thorax. Before we do that, let's review what we've seen of the muscles of respiration.

Here’s the parietal pleura, and the visceral pleura. Here’s the pleural cavity, and the mediastinum. Here’s the dome of the pleura. Here’s the diaphragm, the right and left crus, the vena caval foramen, the esophageal hiatus, the aortic opening.

Here are the external intercostal muscles, the scalene muscles, anterior, middle, and posterior, the internal intercostals. Lastly here are the rectus abdominis, transversus abdominis, internal oblique, and external oblique muscles.
