What bone serves as an attachment point for the ribs?

The sternum serves as the main attachment point for the ribs, specifically providing connection to the true ribs via costal cartilage. This flat bone, commonly referred to as the breastbone, is located in the center of the chest and plays a crucial role in the structure of the ribcage. It helps protect vital organs such as the heart and lungs while also anchoring the ribcage, which expands and contracts during breathing.

Various muscles, including those involved in respiration, also attach to the sternum, highlighting its importance in both structural support and movement. The sternum's design allows for the flexibility of the thoracic cage needed for efficient respiratory mechanics.
