Final answer:
A linear skull fracture is a fracture with radiating fracture lines from the impact point. Other types of fractures include comminuted, depressed, contrecoup, and basilar fractures.
Step-by-step explanation:
A linear skull fracture is a common type of fracture that occurs when there are fracture lines radiating from the point of impact on the skull. Other types of fractures include comminuted fractures, where the bone is broken into several pieces at the point of impact, and depressed fractures, where the fractured bone is pushed inward. A contrecoup fracture occurs on the opposite side of the skull from the point of impact. A basilar fracture, which can be life-threatening, occurs at the base of the skull and may damage the artery passing through the carotid canal.
