The anterior or superior ligament (ligamentum costotransversarium anterius) (Figs. 234 and 235) consists of two sets of fibres; the one (anterior) is attached below to the sharp crest on the upper border of the neck of each rib, and passes.

Seen from above. obliquely upward and outward to the lower border of the transverse process immediately above; the other (posterior) is attached below to the neck of the rib, and passes upward and inward to the base of the transverse process and outer border of the lower articular process of the vertebra above. The first rib has no anterior costotransverse ligament. For the twelfth rib the ligament is absent or is a mere vestige. Relations.—This ligament is in relation, in front, with the intercostal vessels and nerves; behind, with the Longissimus dorsi muscle. Its internal border is thickened and free, and bounds an aperture through which pass the posterior branches of the intercostal vessels and nerves. Its external border is continuous with a thin aponeurosis which covers the External intercostal muscle. The middle costotransverse or interosseous ligament (ligamentum colHcostae} (Fig. 234) consists of short but strong fibres which pass between the rough surface on the posterior part of the neck of each rib and the anterior surface of the ad- jacent transverse process.
