What is the general term for brain tissue being squeezed through structures in the cranium?

• A. Herniations
• B. Edema
• C. Hematoma
• D. Contusion

Answer: (A)

The main idea here is tissue displacement due to rising pressure inside the skull. When brain tissue is forced through openings or under edges of skull structures like the falx cerebri or tentorium, this movement is called herniation. It’s a dangerous, life-threatening process because it can compress vital brain regions, especially the brainstem. Edema describes swelling from fluid buildup, which can raise pressure but does not itself mean tissue is being pushed through skull structures. Hematoma is a localized collection of blood that can cause mass effect, and contusion is bruising of brain tissue; neither term describes the process of tissue being squeezed through intracranial structures.
