What does meninx mean?
Meninx is the singular anatomical term for a membrane surrounding the brain or spinal cord, and it is especially associated with the dura mater, the tough outer protective layer. The word is used mainly in medical contexts, where precision about the brain’s coverings is important. In general writing, meninges is much more common, especially in the plural. Even so, meninx is useful because it identifies the singular form directly and reflects the vocabulary of anatomy, neurology, and surgery. A distinction is often made among the principal coverings of the brain: the dura mater outside, the arachnoid membrane in the middle, and the pia mater directly adjoining the brain and spinal cord. The term should be understood in that anatomical framework rather than as a general synonym for every surrounding tissue.
