The cranial nerves of vertebrates, when compared with the spinal nerves, show a great diversity in configuration, distribution, and function and the same diversity can also be noted in their development in the embryo. To start with, the two most anterior nerve pairs, nerves I (olfactory) and II (optic), are completely different in nature and cannot be in any way [...]
We will first trace the features manifest in the development of the brain in all vertebrates and then point out some of the peculiarities found in higher vertebrates, especially in mammals and in man. The anterior brain vesicle, the prosencephalon, gives rise at its anterior end to the telencephalon. The latter produces in an early stage two bulges directed anterolaterally [...]
In this article we will discuss about:- 1. Introduction to the Development of Central Nervous System 2. Later Development of the Spinal Cord 3. Dependence in Development of Nerves and Nerve Centers on Peripheral Organs 4. Development of the Autonomic Nervous System. Introduction to the Development of Central Nervous System: The central nervous system of vertebrates develops from the primary [...]
