Final answer:
True. A subgaleal hematoma lies over the skull but under the scalp.
Step-by-step explanation:
True. A subgaleal hematoma does indeed lie over the skull but under the scalp. A subgaleal hematoma is a collection of blood that forms between the galea aponeurotica (a layer of connective tissue) and the periosteum (a layer covering the skull). It typically occurs as a result of trauma or injury to the head, and can lead to swelling and increased pressure on the brain if left untreated.
