Detailed explanation-1: -Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater.
Detailed explanation-2: -Your pia mater, the innermost layer, is a thin layer that’s held tightly-like shrink wrap-to the surface of your brain and spinal cord. Many blood vessels pass through this layer to supply your brain tissue with blood. It also helps contain cerebrospinal fluid.
Detailed explanation-3: -Pia mater (/ˈpaɪ. ə ˈmeɪtər/ or /ˈpiːə ˈmɑːtər/), often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. Pia mater is medieval Latin meaning “tender mother". The other two meningeal membranes are the dura mater and the arachnoid mater.
