Final answer:
Whiplash injuries are most commonly associated with rear-end automobile collisions due to the stretching or tearing of the anterior longitudinal ligament in the neck from the impact.
Step-by-step explanation:
Whiplash injuries are most commonly associated with rear-end automobile collisions. This type of injury occurs when the anterior longitudinal ligament, which runs down the anterior side of the vertebral column and unites the vertebral bodies, is stretched or torn due to extreme posterior bending of the head and neck. This is typically as a result of the abrupt forces exerted on the neck by the impact of a rear-end collision. installation of seat headrests has been instrumental in reducing the occurrence of these injuries.
