A car strikes a tree, causing the passenger to strike his forehead against the dashboard. After the impact, the brain bounces back and forth within the skull. Based on the anatomy and physiology of the skull, which one of the following is true?
◦ The ridges of the basilar skull can injure the brain as it moves back and forth.
◦ The brain will not be injured unless an object on the dashboard penetrates the skull.
◦ The brain will not be injured because the flexibility of the skull will absorb the force of the impact.
◦ The frontal bone is the thinnest portion of the skull and is the most easily fractured.
