True or False: A subgaleal hematoma lies over the skull but under the scalp.

A subgaleal hematoma is indeed a collection of blood that occurs between the outer layer of the skull and the galea aponeurotica, which is the fibrous tissue that connects the muscles of the scalp. This type of hematoma results from the rupture of blood vessels during delivery in infants or can occur due to trauma in other contexts.

The defining characteristic of a subgaleal hematoma is that it is positioned above the skull but beneath the scalp, making it different from other types of hematomas such as epidural or subdural hematomas, which are located in different anatomical spaces related to the brain and more inner layers of the protective membranes.

The configuration of a subgaleal hematoma allows it to spread widely due to the loose nature of the connective tissue underneath the galea, and it can result in significant swelling of the scalp. Understanding this anatomical relation is crucial for healthcare professionals in diagnosing and managing such conditions.
