Question

What does the central nervous system consist of?

Answer 1

The brain and the spinal cord.

Explanation:

The Central Nervous System comprises the brain and the spinal cord.

It is called Central because it coordinates all bodily activity and integrates all information received from various parts of the body through the Peripheral Nervous System.

The brain is housed in the cranium, a thick bony structure that protects it from shock and injury, while the spinal cord, which proceeds from the brain, is encased in the vertebral column, a sequence of bones called vertebrae separated by cartilaginous discs for flexibility.

Both the brain and the spinal cord are encased in a thick protective sheath called the meninges.
