Question

The function of the anterior longitudinal ligament on the vertebral bodies is

A) to prevent hyperextension of the back.
B) to allow for extensive lateral movement and rotation of adjacent vertebrae.
C) to protect the spinal nerve cord.
D) to hold the vertebral laminae together.

Answer 1

The anterior longitudinal ligament prevents hyperextension of the back, running along the front of the vertebral column and limits excessive backward movement to avoid injuries like whiplash.

Step-by-step explanation:

The function of the anterior longitudinal ligament on the vertebral bodies is to prevent hyperextension of the back. This ligament runs along the anterior aspect of the vertebral column, uniting the vertebral bodies, and is necessary for maintaining the structural integrity of the spine.

It specifically resists excess backward bending, which is critical in avoiding injuries such as whiplash, especially in the neck region. Whiplash injuries were more common in the past before the adoption of mandatory seat headrests in vehicles.
