The sternum of a rat, like in other mammals, serves as a central point of attachment for the ribs, contributing to the ribcage's structural integrity and protecting vital organs such as the heart and lungs. It provides leverage for respiratory muscles, aiding in breathing by allowing the ribcage to expand and contract. Additionally, the sternum plays a role in supporting the overall posture and movement of the rat. Overall, it is crucial for both protection and respiratory function.

Why is the sternum germinativum so important?

The sternum germinativum, also known as the germinal layer of the sternum, plays a crucial role in the development and growth of the sternum and surrounding structures. It is responsible for the production of cartilage and bone cells, facilitating the proper formation and fusion of the sternum during early development. This layer ensures the structural integrity of the rib cage, which is vital for protecting internal organs and supporting respiration. Additionally, any abnormalities in the germinal layer can lead to congenital defects in the sternum, impacting overall thoracic function.
