Model No: QH3339-15
Model of Human Embryo Development
Quantity :
This enlarged model can be dissectable in to 17 parts. After the egg is fertilized, the pronucleus is formed,
and the cleavage begins to form two blastomeres that divide to the morula. The blastocyst forms the
blastocyst. The hypoderm (yellow) and epiderm (blue) appear in the inner cell mass, when the
semimembranous cavity is formed. Until the spinal cord is formed, the neural crest is formed and
differentiated, the digestive tract, pharynx, bronchi, esophagus, and gastrointestinal liver are initially
formed, the three brain vesicles progress and evolve, and nerve buds appear on the upper and lower
limbs.
