Journal Entry 6 - Tenzin Lhamo

This week my mentor taught me about the upper part of our body. The sternum, which is also known as the breast bone is connected to our ribs, although not all of our ribs are connected to the sternum. The upper sternum is called the Manubrium and the lower is called the Body. Both the Manubrium and Body are connected with only 6 ribs even though we have 10 ribs. It is because some of our ribs are connected with other ribs, through the Costal (hyaline) cartilage.

In total, we have 20 ribs, 10 in each side, both left and right. We have ribs because they protect our lungs, heart and kidneys. It is amazing to find out how important our ribs are.
