Study Notes

Rib Classification

True ribs (vertebrosternal) are ribs 1-7, with direct attachment to the sternum.
False ribs consist of two types:
- Vertebrochondrial: ribs 8 and 9, and part of rib 10, with indirect attachment to the sternum via cartilage.
- Vertebral: ribs 11 and 12, having no anterior attachment to the sternum.

Types of Ribs

Vertebrosternal ribs have cartilage that directly connects to some part of the sternum.
Vertebrochondrial ribs do not attach directly to the sternum; their cartilages merge with the cartilage of the superior rib.
Vertebral ribs lack any anterior cartilage and do not attach to the sternum at all.

Individual Rib Attachments

Rib 1 attaches to the manubrium of the sternum.
Rib 2 connects to both the manubrium and the body of the sternum.
Ribs 3, 4, 5, and 6 are all attached to the body of the sternum.
Rib 7 attaches to the body of the sternum and partially to the xiphoid process.
Rib 8's cartilage merges with that of rib 7.
Rib 9's cartilage merges with the cartilage of rib 8.
Rib 10's cartilage merges with that of rib 9.
Ribs 11 and 12 have no anterior attachment to the sternum.

Rib Connections

Ribs have two points of attachment: to thoracic vertebrae and to the transverse process of each vertebra.
