LIGAMENTS OF THE YEETEBEAL COLUMN. 307 the fibro-cartilages are thinnest on their anterior aspects in correspondence with the anterior concavity of this section of the vertebral column. Each fibro-cartilage consists of a circumferential portions, annulus fibrosus, formed for the most part of oblique parallel fibres running from one vertebra to the other; horizontal fibres are also found. The axial or central part of the fibro- cartilage, the nucleus pulposus, is elastic, soft, and pulpy. The superior and inferior surfaces of the fibro-cartilage are closely adherent to the adjoining epiphyseal plates of the vertebral bodies, and as ossification advances, the distinction between epiphyseal plates and vertebral body disappears. As a rule the transverse diameter of the fibro-cartilage corresponds to that of the vertebral bodies which it joins together; but in the cervical region, where the inferior margin of the super-imposed vertebra is overlapped on each side by the one which bears it, the fibro-cartilage does not extend to the extreme lateral margin, and in this position a small diarthrosis may be seen at each lateral margin of the fibro-cartilage. Lig\ Longitudinale Anterius. — The anterior longitudinal ligament ( anterior common ligament) (Fig. 293) consists of a wide stratum of longitudinal fibres which extends from the front of the epistropheus vertebra to the front of the superior segment of the sacrum, and becomes gradually wider from above downwards. It lies on the anterior surfaces of the intervertebral fibro-cartilages, to which it is firmly attached as it passes from one vertebra to the other. Its fibres vary in length. Some are attached to contiguous margins of two adjoining vertebras; others pass in front of one vertebra to be attached to the next below, and yet others find their lower attachment three or four vertebras below the one from which they started. None of the fibres are attached to the transve
