Anatomical Relations
Superior fibers of the radiate ligaments extend to the vertebral bodies above, while inferior fibers may extend to the vertebral bodies below. Short intermediate fibers extend horizontally to the intervertebral disc.
Function
The radiate ligaments of the head of the ribs ensure that the ribs are kept in close contact with the vertebral bodies, ensuring only slight gliding movements occur at the joint.
