Early embryo germlayer: 15-18 days following conception , ectoderm, nervous system and skin, hair, fingernails, mesoderm, muscles, joints, and circulatory systems, endoderm, digestion and respiratory systems. Neurulation: forming the neural tube: kandel, schwartz, and jessell (eds. ), principles of neuroscience (4th ed. , p. 1020, fig. Errors in neurulation: anencephaly (anterior portion of tube fails to close, myelomeningocele spina bifida (posterior portion of tube fails to close) spina bifida_diagram. The development of neurons: the development of neurons in the brain involves the following processes, proliferation (neurogenesis, migration, differentiation, myelination, synaptogenesis. Neurogenesis: precursors to neurons and glia begin to form by 6th week, when do neurons stop being produced, postnatal neurogenesis? fig04_01. Differentiation: differentiation refers to, outgrowth of axons and dendrites from the cell body, axon grows first (during migration or once it reaches target); followed by growth of dendrites.
