Mesenchyme cells in the spinal meninges primarily originate from the mesoderm and neural crest cells during embryonic development. Here's how they contribute to the formation of the spinal meninges: 1. Mesoderm: The mesoderm forms the dura mater, the outermost tough layer of the meninges. 2. Neural Crest Cells: Neural crest cells migrate and differentiate into the arachnoid mater and pia mater, the two inner layers of the meninges collectively known as the leptomeninges. These mesenchymal cells migrate, proliferate, and organize into the layers of the meninges during embryogenesis, contributing to the protection and support of the central nervous system.
Thank you so much🥺❤ you've saved me. I'm to do a presentation on this topic and I'm so happy I came across your video
❤️ I'm glad that the video was helpful
Please where are the mesenchyme cells from and how do they aid in the formation of the meninges
