Give scientific reasons for the following statements:
The central nervous system is very well protected.

Explanation

The central nervous system comprises of a brain and a spinal cord.
Brain is contained in a fluid-filled balloon which absorbs mechanical shocks and thereby protect it from any severe injuries. Moreover, the brain is enclosed in a strong bony box-the cranium of the skull and the spinal cord is enclosed in a long and strong bony vertebral column. Thus, the central nervous system (of the human) is very well protected.
