Watch this animation (http://openstaxcollege.org/l/braindevel) to examine the development of the brain, starting with the neural tube. As the anterior end of the neural tube develops, it enlarges into the primary vesicles that establish the forebrain, midbrain, and hindbrain. Those structures continue to develop throughout the rest of embryonic development and into adolescence. They are the basis of the structure of the fully developed adult brain. How would you describe the difference in the relative sizes of the three regions of the brain when comparing the early (25th embryonic day) brain and the adult brain?

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.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
