For what anatomical reason do many women appear to be slightly knock-kneed?_______________________________________________________________ The human rib cage is made up of 12 paired rib bones; each are symmetrically paired on a right and left side. They articulate with the vertebral column posteriorly, and terminate anteriorly as cartilage (known as costal cartilage). The floating ribs are comparatively smaller and have cartilaginous tips. All rights reserved. All ribs are attached posteriorly to the thoracic vertebrae. This region articulates primarily with the costal facet located on the body of the same numbered thoracic vertebra and to a lesser degree, with the costal facet located on the body of the next higher vertebra.
