Summary Introduction

To write:

The differences between in the relative sizes of the three regions of the brain in case of early brain and adult brain.

Introduction:

The brain is the central organ of the central nervous system. The forebrain, the midbrain, and the hindbrain form the three primary portions of the brain during the early development of the central nervous system. The midbrain is associated with the vision, hearing, sleep, temperature control and is divided into the tectum, the cerebral aqueduct, tegmentum, and the basic pedunculi. The forebrain includes the cerebral hemispheres, the thalamus, and the hypothalamus. The hindbrain includes the medulla, pons, and cerebellum.

Explanation of Solution

The primary vesicles form these three basic regions of the brain called the forebrain, midbrain, and the hindbrain. Brain vesicles are the bulge-like structures found in the early development of the neural tube. They form the three primary brain vesicles called the prosencephalon (forebrain), mesencephalon (midbrain) and rhombencephalon (hindbrain). In the early brain stages, these three structures are of the same size when they are first established. The midbrain in the adult is smaller than the other two parts, the forebrain and the hindbrain which increase in the size compared to the early brain of the embryonic stage.

Conclusion

Thus, the difference between the early brain parts and the adult brain is in the size of the forebrain and hindbrain increasing in size.
