The first rib aiculates with the sternum in close proximity to the?
The first rib aiculates with the sternum directly below the sternoclavicular joint. The nipple is found in the fouh intercostal space, between the 4th and 5th ribs. The sternal angle is connected to the costal cailage of rib 2. Finally, the xiphoid process is located just below the point where the costal cailage of rib 7 aiculates with the sternum. The root of the lung, or hilum, is the point where the main bronchus, pulmonary vessels, bronchial vessels, lymphatic vessels, and nerves enter and leave the lung.
