Your sternum is a bone that’s located in the middle of your chest. It’s also sometimes referred to as the breastbone. Your sternum protects the organs of your torso from injury and also serves as a connection point for other bones and muscles.
Several muscles that move the arms, head, and neck have their origins on the sternum. It also protects several vital organs of the chest, such as the heart, aorta, vena cava, and thymus gland that are located just deep to the sternum. The sternum is located along the body’s midline in the anterior thoracic region just deep to the skin.
Its three regions are the manubrium, the body, and the xiphoid process. The word “sternum” originates from the Greek στέρνο, meaning “chest”. The sternum is a long, flat bone, forming the middle portion of the front of the chest.This diagram with labels depicts and explains the details of Sternum Location.
