Brain Protection and Major Divisions — NEET Biology
📚 Practice Concept📖 NCERT Source
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. The brain can be divided into three major parts: (i) forebrain, (ii) midbrain, and (iii) hindbrain.

The brain is divided into three main regions: forebrain, midbrain, and hindbrain, all clearly labeled. (Figure 18.4 Diagram showing sagittal section of the human brain)
