Final answer:
Hangings are associated with hyperextension injury mechanism, where the neck is forcefully extended backward.
Step-by-step explanation:
Hangings are associated with hyperextension injury mechanism. Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, resulting in injury. In cases of hangings, the sudden and intense force applied to the neck causes the head to be forcefully extended backward, resulting in hyperextension of the cervical region.
