Question

What 2 regions do the ribs articulate with?

Answer 1

Hlo_ here's Ur Answer ⬇️

Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint. An exception to this rule is that the first rib articulates with the first thoracic vertebra only. According to their attachment to the sternum, the ribs are classified into 3 groups: true, false, and floating ribs[4].
