solution:

The human cerebrum is ensured by the skull. Inside the skull, there are cranial meninges that cover the cerebrum. The cranial meninges are comprised of three layers, to be specific – Dura mater (external layer), Arachnoid (center layer) and Pia mater (inward layer which is in touch with the cerebrum). Dura mater is the thick, extreme, stringy layer. Arachnoid is a layer with an insect like design. The boundary is an exceptionally dainty, fragile and vascular film. The space between dura mater and arachnoid is called subdural space. The space among arachnoid and boundary is called subarachnoid space. It is filled cerebrospinal liquid which goes about as a pad for CNS from shock.
