does not exist; but the fibers of the ligament in each case are connected to the vertebra above, as well as to that with which the rib articulates.

The Interarticular Ligament (ligamentum capituli costæ interarticulare).—The interarticular ligament is situated in the interior of the joint. It consists of a short band of fibers, flattened from above downward, attached by one extremity to the crest separating the two articular facets on the head of the rib, and by the other to the intervertebral fibrocartilage; it divides the joint into two cavities. In the joints of the first, tenth, eleventh, and twelfth ribs, the interarticular ligament does not exist; consequently, there is but one cavity in each of these articulations. This ligament is the homologue of the ligamentum conjugale present in some mammals, and uniting the heads of opposite ribs, across the back of the intervertebral fibrocartilage.

Synovial Membranes.—There are two synovial membranes in each of the articulations where an interarticular ligament exists, one above and one below this structure; but only one in those joints where there are single cavities.

2. Costotransverse Articulations (articulationes costotransversariæ) (Fig. 313).—The articular portion of the tubercle of the rib forms with the articular surface on the adjacent transverse process an arthrodial joint.
  In the eleventh and twelfth ribs this articulation is wanting.
  The ligaments of the joint are:
The Articular Capsule.
The Posterior Costotransverse.
The Anterior Costotransverse.
The Ligament of the Neck of the Rib.
The Ligament of the Tubercle of the Rib.
