Developmental Biology
Chapter 6: Development of the vertebrate germ layers anogenesis (I)
Development of the vertebrate germ layers anogenesis
1 Development of the vertebrate germ layers
Ectoderm
Paraxial and intermediate mesoderm
Lateral plate mesoderm and endoderm
2 Development of the nervous system
The specification of neural cell identity ( neuron or glial cell)
Migration of neurons and the guided outgrowth of axons toward their target cells
Synapse formation and refinement
3 The limb development
Formation of the limb bud and limb outgrowth
Generation of the proximal-distal axis of the limb
Specification of the anterior-posterior limb axis
Generation of the dorsal-ventral axis
Coordinating the three axes
Development of the digits
4 Formation of ans: blood vessels, lungs, kindney, heart, and teeth (Option)

Major derivatives of the ectoderm germ layer
dorsal
ventral
Major derivatives of the mesoderm germ layer
The major function of the embryonic endoderm is to construct the linings of two tubes within the vertebrate body
The digestive tube and its derivatives (liver, gallbladder, and pancreas)
