The weight of an adult brain.

Introduction:

The nervous system of a human is divided into two subdivisions: the central nervous system or CNS (includes the spinal cord and the brain) and the peripheral nervous system or PNS (includes rest all parts of the nervous system except spinal cord and brain).

Expert Solution & Answer

Explanation of Solution

The brain, which is a part of the central nervous system of a vertebrate, has changed a lot during evolution while the spinal cord has evolved very little. The weight of the brain is similar to that of the spinal cord in most of the vertebrates, while in humans, it is 55 times more than that of the spinal cord.

In humans, the brain of an adult male weighs about 1,600 g while in females it weighs about 1,450 g. The difference is due to the difference in body size between the two sexes and is not related to intelligence.

Conclusion

The typical weight of an adult brain in human males is about 1,600 g, and in an adult female, it is about 1,450 g.
