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.
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. It supplies the place of the ligamenta flava , and is in relation, behind, with the obliqui capitis inferiores .
The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conduits for the spinal nerves.
The superficial dorsal sacrococcygeal ligament (ligamentum sacrococcygeum posterius superficiale) originates on the free margin of the sacral hiatus to attach on the dorsal surface of the coccyx. It closes the posterior aspect of the most distal part of the sacral canal and corresponds to the ligamenta flava .
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 vertebrae. [5] The ligaments are narrow and elongated in the thoracic ...
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.
A ligament is the fibrous connective tissue that connects bones to other bones. It also connects flight feathers to bones, in dinosaurs and birds. All 30,000 species of amniotes (land animals with internal bones) have ligaments. It is also known as articular ligament, articular larua, [1] fibrous ligament, or true ligament.
The tectorial membrane of atlanto-axial joint (occipitoaxial ligaments) is a tough membrane/ [1] broad, strong band [2] representing the superior-ward prolongation of the posterior longitudinal ligament (the two being continuous). [3] [1] [2] It attaches inferiorly onto (the posterior aspect of [2]) the body of axis. [3] It broadens superiorly.
