Root of vertebral arch divided The laminae of adjoining vertebrae are bound together by the ligamenta flava ((IT. subflava) (Fig. 295), which consist of yellow elastic fibres. The ligamenta flava close the vertebral canal in the intervals between the laminae. Each ligament is attached superiorly to the anterior aspect of one lamina at a short distance above its inferior border, and interiorly it is attached to the posterior aspect of the subjacent lamina. In the thoracic region, where the imbrication of adjoining laminae is a prominent feature, these ligaments are not so distinctly visible from behind as they are in the regions where imbrication of the laminae is not so marked. Laterally they extend as far as the articular capsules, while medially the margins of the ligaments of opposite sides meet under cover of the root of the spinous process. Contiguous spinous processes are also attached to each other by ligamenta interspinalia (interspinous ligaments) (Fig. 292). These are strongest in the lumbar, and weakest in the thoracic region. Each consists of layers of obliquely inter- lacing fibres which spring from near the tips of the two adjacent spinous process and radiate to their op- posing margins. In the antero - posterior direc- tion they extend from the base to the tip of the spinous process. The ligamenta supra- spinal (supra-spinous ligaments) (Fig. 292) consist of longitudinal bands of fibres of varying lengths. They extend from spine to spine, being attached to their tips, and are situated superficial to, although in continuity with, the ligamenta interspinalia. In the cervical region this series of ligaments is extensively developed, where they project back- wards from the spinous processes between the muscles of the two sides of the neck in the form of an elastic partition called the ligamentum nuchas. The antero-posterior extent of the ligamentum nuchae increases as it approaches
