Anatomy, Comparative. 48 COMPARATIVE ANATOMY them throughout life by sutures, as is the case iu certain Reptiles: even the ligament which keeps the odontoid process of the axis in its place may become ossified. Fibro-cartilaginous discs or menisci are present between the centra. In the cervical region, which is extremely flexible and often very long, the centra are in nearly all cases connected by means of saddle-shaped synovial articulations; the upper part of the bifurcated transverse processes arises from the arch, the lower from the centrum, and these may unite with the corresponding forked rib, the vertebral artery and vein extending through the foramen thus formed (Fig. 36). In the thoracic and lumbar regions more or fewer of the vertebrae usually become immovably united .together. The sacral region in Bird-embryos, like that in existing adult Reptiles, consists of tivo vertebras only, the transverse processes of.
