What is the medical term for the inflammation of the meninges?

The correct medical term for the inflammation of the meninges is meningitis. Meningitis refers specifically to the swelling and inflammation of the protective membranes (meninges) that surround the brain and spinal cord. Inflammation can be caused by infections (such as viral, bacterial, or fungal), autoimmune diseases, or even certain medications.

Other terms mentioned in the options pertain to different conditions. Encephalitis refers to the inflammation of the brain itself, typically due to viral infections. Neuritis signifies inflammation of a nerve, which can affect the nerve function but does not specifically involve the meninges. Meningioma, on the other hand, refers to a type of tumor that arises from the meninges, not inflammation. Thus, the distinction between these terms highlights why meningitis is the correct answer for the inflammation of the meninges.
