What does a meningioma affect?

• A. Coverings of the brain
• B. Blood vessels of the brain
• C. Neurons
• D. Neuroglia

Answer: (A)

A meningioma is a type of tumor that arises from the meninges, the protective layers covering the brain and spinal cord. It primarily affects the coverings of the brain, as these layers are made up of several types of cells that can proliferate to form a tumor. These tumors can occur in various locations, often leading to localized pressure on the brain or spinal cord depending on their size and growth pattern. Symptoms associated with meningiomas can arise due to the displacement of brain tissues or by affecting nearby structures. This highlights the importance of understanding the relationship between meningiomas and the protective membranes of the central nervous system. Other options involve brain components such as blood vessels, neurons, and neuroglia, but these are not the primary targets of a meningioma. Therefore, the focus on the coverings of the brain is what distinguishes the correct response.
