during gastrulation process? How gastrulation occur in primitive chordate? How gastrulation occurs in amphibian? How gastrulation occurs in sea urchin? How gastrulation occur in chick? How gastrulation occur in bird and mammals?

Epithelial movement

There are 5 process in epithelial movement which is: -Epiboly -Invagination -Involution -Convergent adhesion -Delamination

What happen during epiboly? What happen during invagination? What happen during invagination? What Happen during convergent

Actions Discuss with group members. Refers to text books. Surfing internet. Reading the journal. Discuss with Dr.Hayati.
