What are the three layers of membranes that protect the nervous tissue called?

The three layers of membranes that protect the nervous tissue are known as the dura mater, arachnoid mater, and pia mater. These layers, collectively referred to as the meninges, serve crucial roles in safeguarding the brain and spinal cord. The dura mater is the outermost, tough layer that provides a robust protective barrier against physical impact. The arachnoid mater is the middle layer, which is web-like and situated between the dura and pia mater, containing cerebrospinal fluid that cushions the brain and spinal cord. The pia mater is the innermost layer, closely adhering to the surface of the brain and spinal cord, and it contains blood vessels that supply nutrients to the nervous tissue. This tri-layered structure is essential for protecting the central nervous system from injury and infection, as well as maintaining an appropriate environment for neuronal function.
