Contrast involution, epiboly, and convergent extension.

#Unit 5. Developmental Biology

Involution is the movement of cells toward an axis to extend that axis, epiboly is a flattening and spreading of epithelial cells to increase the amount of surface they cover, and convergent extension is the movement of cells inside the embryo as a coherent sheet.
