When both the entire brain shifts forward hitting the frontal bone and snapping veins/arteries, resulting in anterior and posterior bleeds, what is this known as?

  1. Contra contra shift

  2. Contra coup

  3. Coup shift

  4. Coup contra

The correct answer is: Contra coup

This condition is known as a "contra coup injury." In a contra coup injury, the brain shifts forcefully against the inside of the skull, creating two points of impact - one where the initial injury occurs and one where the brain rebounds and hits the opposite side of the skull. This can result in damage to blood vessels and bleeding in both the front and back of the brain. The other options provided do not accurately describe this specific type of brain injury.
