The ligamenta flava (sg.: ligamentum flavum, Latin for yellow ligament) are a series of ligaments that connect the ventral parts of the laminae of adjacent vertebrae. They help to preserve upright posture , preventing hyperflexion , and ensuring that the vertebral column straightens after flexion.
They extend from the root to the apex of each spinous process. They meet the ligamenta flava anteriorly, [4] [better source needed] and blend with the supraspinous ligament [3] posteriorly at the apexes of the spinal processes. The function of the interspinous ligaments is to limit ventral flexion of the spine and sliding movement of the ...
The costovertebral joints are the joints that connect the ribs to the vertebral column. The articulation of the head of rib connects the head of the rib and the bodies of vertebrae. The costotransverse joint connects the rib with the transverse processes of vertebrae.
Superior to the 7th cervical vertebra, the supraspinous ligament is continuous with the nuchal ligament. [ 2 ] : 45 It is thicker and broader in the lumbar region than in the thoracic region, and intimately blended with the neighboring fascia in both these regions. [ 3 ]
The vertebral canal is enclosed anteriorly by the vertebral bodies, intervertebral discs, and the posterior longitudinal ligament; it is enclosed posteriorly by the vertebral laminae and the ligamenta flava; laterally, it is incompletely enclosed by the pedicles with the interval between two adjacent pedicles on either side creating an intervertebral foramen (allowing the passage of the spinal ...
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the laminæ of the axis.
The posterior internal vertebral venous plexus [2] consists of two veins situated - one on either side - upon the anterior aspect of the vertebral arches and ligamenta flava. They form anastomoses with posterior external plexuses by way of veins passing through or between the ligamenta flava.
The superficial dorsal ligament corresponds to the ligamenta flava and closes the posterior aspect of the distal end of the vertebral canal. [1] It stretches from median sacral crest [3] and the free margin of the sacral hiatus [1] to the dorsal surface of the coccyx. [1]
