    from the dura matter of the spinal cord by those veins and some loose cellular and adipose tissue. Articular Processes.—The ligaments of the articular pro- cesses of the vertebrae are thin layers of lii^amentous fibres which surround and inclose the synovial membranes ; the latter being looser in the cervical than in the other regions of the spine. Spinous Processes.—The inter-spinous ligaments, thin and membranous, are extended between the spinous processes in the dorsal and lumbar regions. They are thickest in the latter; and are in relation with the multifidus spinae muscle, at each side. The supraspinous ligament is a strong fibrous cord, which extends from the apex of the spinous process of the last cervi- cal vertebra to the sacrum, being attached to each spinous pro- cess in its course ; like the anterior and posterior common liga- ments, it is composed of fibres of unequal length, the deeper fibres passing from one vertebra to the next, the superficial fibres extending over several spinous processes ; it is thickest in the lumbar region. The continuation of this ligament upwards to the tuberosity of the occipital bone, constitutes the rudiment- ary ligamentum nucha? of man. The latter is strengthened, as in animals, by a thin slip from the spinous process of each cervi- cal vertebra. Transverse processes.—The inter-transverse ligaments are thin and membranous ; they are found only between the transverse processes of the lower dorsal vertebrae. 2. Articulation of the Atlas with the Occipital Bone.—The ligaments of this articulation are seven in number— Two anterior occipito-atloid, Posterior occipito-atloid, Lateral occipito-atloid, Two capsular. Of the two anterior ligaments, one is a rounded cord, situated in the middle line, and superficially to the other. It is attached, above, to the basilar process of the occipital bone ; and, below to the anterior tubercle of the atlas. The deeper ligament is a />roac^ membranous layer, attached, above, to the margin of the occipital foramen between the two condyles; and, below, to the whole length of the anterior arch of the atlas. It is in relation in front, with the recti antici minores; and, behind, with the odontoid ligaments. The posterior ligament is thin and membranous : it is attached, above, to the margin of the occipital foramen between the two condyles ; and, below, to tlie ])Osterior arch of the atlas. It is closely adherent to the dura mater by its inner surface ; and forms a ligamentous arch at each side, for the passage of the vertebral
