A superior costotransverse ligament is a strong fibrous band that arises from the neck of a
rib
In vertebrate anatomy, ribs ( la, costae) are the long curved bones which form the rib cage, part of the axial skeleton. In most tetrapods, ribs surround the chest, enabling the lungs to expand and thus facilitate breathing by expanding the ches ...

above. It comprises two sets of fibers. The anterior set passes obliquely superiorly and laterally from the sharp crest on the superior border of the neck of each rib to the anterior surface of the transverse process of the vertebra immediately superior to it. The posterior set passes superiorly and medially from the crest on the superior border of the neck of the rib to the inferior border of the transverse process of the vertebra immediately superior to it. The ligament may be absent for the first rib.
