Question

Quizplus · Accepted Answer

The anterior longitudinal ligament acts to prevent hyperextension of the spine, or excessive backwards bending, by limiting the range of motion in that direction. This helps to protect the discs and maintain the stability of the vertebral column. While the ligament does provide some support, its main function is to limit hyperextension. The spinal cord is protected primarily by the vertebrae themselves and the meninges, not by the anterior longitudinal ligament. While the ligament may help to hold the discs in place to some degree, that is not its primary function. Holding the spine erect is a function of many muscles and other ligaments, not just the anterior longitudinal ligament.
