Janis tore a ligament in her ankle. Until the injury heals, she is at most risk for which of the following? dislocating bones lo
bulgar [2K]

Answer:

The correct answer is ''dislocating bones.''

Explanation:

When the bone " pops out" or dislodges from its place (joint), a dislocation occurs. An ankle dislocation, like any other joint, occurs when the 2 articular surfaces of the ankle separate, in this case when the talus ( together with the rest of the foot) " pops out of place" and is no longer in contact with the surface of the tibia-fibula. This leads to the complete breakdown of the ligaments that hold the joint in place, causing the bones to " pops out." Producing significant deformities in the affected joint.

The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone.
