Ribs
Structure and Composition:
- The rib cage consists of 24 ribs, 12 on each side of the body.
- Ribs are categorized into true ribs (first seven pairs), false ribs (next three pairs), and floating ribs (last two pairs).
- True ribs attach directly to the sternum via costal cartilages, false ribs attach indirectly, and floating ribs do not attach to the sternum.
Functions:
- Protect vital organs, especially the heart and lungs.
- Provide support for the upper body.
- Assist in breathing by changing the volume of the thoracic cavity.
