Information about Pia Mater

| The medulla spinalis and its membranes. | |
| subject #193 878 | |
| MeSH | Pia+Mater |
The thin, mesh-like pia mater closely envelops the entire surface of the brain, running down into the fissures of the cortex. It joins with the ependyma which lines the ventricles to form choroid plexuses that produce cerebrospinal fluid.
In the spinal cord, the Pia mater attaches to the Dura mater by the denticular ligaments through the arachnoid membrane.
The pia mater is a neural crest derivative.
