Lateral view of Embryos between Week 6 to 8 (Carnegie Stage 17 to 23) showing Craniofacial Morphogenesis

  • Lateral view of embryos between Carnegie stage 17 and 23 showing craniofacial morphogenesis.
  • The dashed line indicates the reference axis (Z-axis) in Method-1 and the red line indicates the reference axis (X-axis) in Method-2.
  • The arrow indicates the frontal side of the face defined in Method-2.

Magnification is identical in all stages. The frontal position defined by Method-2 rotated as stages proceed. Note that both external and internal ears were located at similar positions between Pg and C1 between CS 17 and 23


Legend

  • Ex - external ear
  • int - internal ear
  • Ey - eye
