Name the structures involved in the protection of the brain.
The following structures are involved in the protection of the brain in animals:
(i) Cranium there are 8 cranial bones that form the hard protective outer covering cranium for the brain.
(ii) Meninges the brain is covered with three membranes called meninges.
(a) Pia mater, Innermost membrane very thin, delicate and vascular and invests the brain closely.
(b) Arachnoid membrane is like a spider web in structure from which it gets its name.
(c) Dura mater is an outermost, thick, tough fibrous membrane adhering closely to the inside of the skull.
(iii) Cerebrospinal fluid The cerebrospinal is present in the spaces between the meninges, i.e., arachnoid and dura mater, which function as a pad, absorbing shocks.
