Now let me search the medical library for meninges content in parallel.

Good results. Now let me read the key sections in parallel - Gray's Anatomy for detailed anatomy, Junqueira's for histology, and Neuroscience for functional aspects.

Excellent content. Now let me read more of the Gray's Anatomy meninges section for details on dural folds, spaces, and blood supply, plus fetch the key diagrams.

I now have excellent, comprehensive material from multiple authoritative textbooks. Let me also fetch the meninges cross-section diagram from Neuroscience book and get the dural folds/spaces table content.
