| A | B |
| Induction | process that culminates in the formation of a thickening in the ectoderm germ layer known as the neural plate |
| Neurulation | process by which the neural plate becomes neural tube |
| Endoderm | Structures of the body formed: Internal organs and viscera |
| Mesoderm | Structures of the body formed: Bones and muscles |
| Ectoderm | Structures of the body formed: Nervous system and skin |
| Mitosis | process in cell division by which the nucleus divides, normally resulting in two new nuclei |
| Differentiation | process by which cells or tissues undergo a change toward a more specialized form or function |
| Synaptogeneis | Formation of nerve synapses |
| Myelination | the acquisition, development, or formulation of a myelin sheath around a nerve fiber |
| Myelin sheath | a white fatty substance that surrounds the axon and aids in neural transmission |
| Rostral | Part of the neural tube that develops into the brain |
| Caudal | Part of the neural tube that devlops into the spinal cord |
| Functions of glia | holds neurons in place |
| Functions of glia | provides physical support |
| Stage of development | Aggregation |
