The protective and supportive covering of the brain is known as what?

Explanation:
The protective and supportive covering around the brain is the meninges. This term refers to the three membranes that enclose the brain and spinal cord, providing protection, support, and a channel for cerebrospinal fluid. The outermost layer is the dura mater, a tough protective shell; just inside is the arachnoid mater, a web-like middle layer; and the innermost layer is the pia mater, a delicate membrane that hugs the brain surface. All three together form the meninges. The subdural space is not a covering—it’s a potential space between the dura and arachnoid that can accumulate fluid.
