The thinnest wrapping
Your brain has three wrappings called the meninges. The pia mater is the innermost one, lying right on the brain.
It is made of very flat, thin cells. It is so thin that it dips into every groove and fold of your brain.

Meningeal Pia Mater Cells (Brain Hugging Layer)
The innermost wrapping of your brain is so thin and gentle that it follows every bump and groove, like plastic wrap on a walnut.

Hugging the brain
- It covers and protects the brain's surface.
- Blood vessels travel along it before they dive into the brain, bringing food and oxygen.
- It sits right next to the clear cushion fluid that bathes the brain.
Try this
Press Hug the brain on the 3D model to see the thin pia layer light up on top of the brain.
Wow!
Pia mater means "tender mother" in Latin. Long ago, doctors thought the wrappings cared for the brain like a mother. The tough outer one is called dura mater, "tough mother."
