Study Notes
Intervertebral Disc
- Located between adjacent vertebrae in the vertebral column.
- Composed of intervertebral fibrocartilage.
Anterior Longitudinal Ligament
- Runs along the anterior surface of the spine.
- Covers all vertebral bodies and intervertebral discs.
Posterior Longitudinal Ligament
- Found within the vertebral canal.
- Extends from the body of the axis to the sacrum, covering posterior surfaces of vertebral bodies.
Interspinous Ligaments
- Connect adjoining spinous processes of the vertebrae.
- Thin membranes that run from the root to the apex of each spinous process.
Ligamentum Flavum
- Connects laminae of adjacent vertebrae from the axis to the first sacral segment.
Supraspinous Ligament
- Connects tips of spinous processes from the seventh cervical vertebra to the sacrum.
Ligamentum Nuchae
- Extends from the external occipital protuberance to the spinous process of the seventh cervical vertebra.
Intertransverse Ligament
- Positioned between the transverse processes of the spine.
Anterior Atlanto-Occipital Ligament
- Broad ligament with densely woven fibers.
- Connects the foramen magnum above and the anterior arch of the atlas below.
Posterior Atlanto-Occipital Ligament
- Thin membrane connected to the foramen magnum above and the posterior arch of the atlas below.
Anterior Atlanto-Axial Ligament
- Strong membrane that connects the anterior arch of the atlas to the body of the axis.
Posterior Atlanto-Axial Ligament
- Broad, thin membrane linking the posterior arch of the atlas to the laminæ of the axis.
Lateral Atlanto-Occipital Ligament
- Provides additional support; specifics not detailed.
Transverse Ligament of Atlas
- Thick band that arches across the atlas ring.
- Keeps the odontoid process in contact with the atlas.
Cruciform Ligament
- Holds the dens against the anterior arch of the atlas.
- Consists of transverse ligament (cross-bar) and vertical longitudinal bands that connect to the foramen magnum.
Tectorial Membrane
- Strong band covering the dens and ligaments within the vertebral canal.
- Extensions from the posterior longitudinal ligament.
Alar Ligament
- Connects the sides of the dens to occipital condyle tubercles.
Apical Ligament
- Fibrous cord between alar ligaments.
- Extends from the odontoid process to foramen magnum.
Radiate Ligament
- Joins the head of each rib with the bodies of two vertebrae and intervertebral fibrocartilage.
Lateral Costotransverse Ligament
- Fibrous band that connects transverse process tips to rib tubercles.
Superior Costotransverse Ligament
- Strong fibrous band linking rib necks to the transverse process of the vertebra above.
