Before we move on, let’s briefly review what we’ve seen of the bones of the thorax.
Here are the thoracic vertebrae, and the ribs. Here’s the head of the rib, the tubercle, the neck, and the angle. Here’s the costovertebral joint, and the costo-transverse joint.
Here are the costal cartilages, here’s the costal arch, here’s the sternum the manubrium, the body, and the xiphoid process; the upper thoracic aperture and the lower thoracic aperture.
Here’s the clavicle, the scapula, the sterno-clavicular joint, and the acromio-clavicular joint.
