UNIT 1 - Embryogenesis
This unit will provide the therapist with a basis upon which to expand his/her knowledge of the structure and function of the mature nervous system.
Educational Objectives:
Upon completion of this unit the student will be able to:
1. Identify each primitive embryonic germ layer in cross section given a schematic drawing.
2. List the mature systems that evolve from each primitive germ layer.
3. Identify the stages in the differentiation of the primitive ectoderm by labeling representations of the neural plate, neural groove, and neural tube.
4. Identify the neural crest and dorsal root ganglia given schematic drawings.
5. List, beginning centrally, layers which form with the differentiation of the primitive neural tube in relationship to the ependymal, mantle, and marginal layers.
6. Name the two types of primitive cells that migrate from the ependymal layer and the cells they represent in the adult nervous system.
7. Identify the sulcus limitans given a schematic cross section of the spinal cord and explain in writing its functional significance.
8. Identify the mesencephalic flexure given a lateral view of the brain, and explain in writing how it affects the anatomical alignment of the neuroaxis.
9. Identify the primary and secondary brain vesicles given drawings of different anatomical views of the brain during varying stages of embryogenesis.
