APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -A rib articulates at the junction of the vertebral body and pedicle (superior costal facet) of its named vertebra and the vertebra above (inferior costal facet). The rib also articulates with the transverse costal facet of the transverse process of its named vertebra.

Detailed explanation-3: -The head of each rib articulates with: The lower rib facet articulates with the upper costal facet of its own vertebra. The upper facet articulates with the lower facet of the vertebral body above.

Detailed explanation-4: -Lateral view, inferior surface The superior demifacet of the body of the vertebra receives the head of the rib with the same number as the vertebra of interest. For example, rib 5 articulates with thoracic vertebra 5 at its superior demifacet.
