Study Notes
- The brain consists of the cerebrum, cerebellum, brainstem, and diencephalon.
- The cerebrum is the largest part of the brain and is divided into four lobes.
- The cerebellum is the next largest part of the brain and its surface is also highly folded.
- The brainstem is the more inferior part of the brain and is composed of the medulla, pons, and the midbrain.
- The importance of the brain is reflected in its early development.
- The development of the brain begins with the same processes and organization that we see in the spinal cord.
- In addition to the neurons of the CNS, the neuroepithelial cells also give rise to the neuroglia (support) cells of the CNS.
- The telencephalon is at the very end of the neural tube and it undergoes exuberant growth to form the cerebrum.
- The cerebrum and cerebellum undergoes significant additional differentiation.
- The first indication of this further differentiation is the formation of three “primary vesicles”.
- The cerebrum, cerebellum, and brainstem undergoes additional foldings that transform them from a linear structure to a more blobular structure.
