Chapter 22

6. This section of the developing embryo gives rise to the midbrain.
7. These cells form bicycle-like spokes to aid in neural migration.
11. This section of the developing embryo gives rise to the cerebrum.
13. Which embryonic germ layer gives rise to the lining of the organs?
14. What determines whether cells in the dorsal ectoderm give rise to epidermal or neural cells?
16. This section of the developing embryo gives rise to the pons and cerebellum.
17. In this stage of embryonic development, a folding process creates a tube that is crucial in future development of the brain.

1. The transient section of the coral neural tube that gives rise to interneurons in the spine and hindbrain.
2. The transient section of the dorsal neural tube that gives rise to peripheral sensory neurons and glia.
3. Which embryonic germ layer gives rise to the neural tube?
4. The sharp bend in the neural tube that balloons out into the prosencephalon.
5. In this stage of embryonic development, the cells migrate to create three distinct layers.
8. This section of the developing embryo gives rise to the thalamus and hypothalamus.
9. The division of an organism into repeating units, specifically on the anterior/posterior axis.
10. This section of the developing embryo gives rise to the medulla.
12. These genes influence the segmentation of Drosophila.
15. These formations will later become eyes.
