The stmemum is anterior (ventral) to the heart. Meaning it is in front of the heart.
The manubrium
The sternum is a bone in the chest (thorax). It is part of the skeletal system.
The sternum, commonly known as the breastbone, is located in the center of the chest, anterior to the heart and lungs. It connects to the ribs via cartilage, forming part of the rib cage which protects vital thoracic organs. The sternum consists of three parts: the manubrium, body, and xiphoid process.
The sternum, or breastbone, is a flat bone located in the center of the chest. It serves as a vital component of the ribcage, providing attachment points for the ribs and helping to protect the heart, lungs, and major blood vessels. Additionally, the sternum plays a role in the respiratory system by allowing for the expansion of the thoracic cavity during breathing. Its structure also aids in maintaining the integrity of the chest wall.
The sternum, or breastbone, serves several important functions in the human body. It acts as a central point of attachment for the ribs via costal cartilage, helping to form the ribcage that protects vital organs like the heart and lungs. Additionally, the sternum plays a role in supporting the shoulder girdle and facilitating the movement of the upper limbs. Its structure also aids in the production of blood cells, as it contains red bone marrow.
On an animals body the thorax is located between the head and abdomen. The thorax is a main division of an insects body. In mammals, thorax is formed by the stemum, thoracic vertebra and ribs.
