Study Notes
Rib Cage Overview
- Total of 24 ribs in the human body, classified into three categories: true ribs, false ribs, and floating ribs.
True Ribs
- First seven pairs of ribs (1-7).
- Connect to the spine via ligaments at the back.
- Attach to the sternum at the front through costal cartilage.
False Ribs
- Comprise the next three pairs of ribs (8-10).
- Connected to the spine at the back like true ribs.
- Do not connect directly to the sternum; instead, they link to the last two true ribs via cartilage.
Floating Ribs
- Last two pairs of ribs (11-12), the smallest in the rib cage.
- Are not attached to the sternum or to each other in the front, creating the "floating" appearance.
- Attached only to the spine at the back.
