The brain is the central information processing organ of our body, and acts as the ‘command and control system’.
The human brain is well protected by the skull.
Inside the skull, the brain is covered by cranial meninges consisting of an outer layer called dura mater, a very thin middle layer called arachnoid and an inner layer (which is in contact with the brain tissue) called pia mater.
Cerebrospinal fluid fills the space between the arachnoid and pia mater layers to cushion the brain from any mechanical shock.
The brain can be divided into three major parts: (i) forebrain, (ii) midbrain, and (iii) hindbrain
