  mesenchymal epithelial transition, that separates the developing digits

2 Which of the following statements about cleft lip is most correct

  cleft lip is failure of the maxillary prominences to fuse with the medial nasal prominences
  cleft lip is failure of the maxillary shelves to fuse with the medial nasal prominences
  cleft lip is failure of nasal septum to fuse with the maxillary prominences
  cleft lip occurs during the early fetal period
  cleft lip occurs due to a single known teratogen

3 Bone formation by endochondral ossification:

  only occurs in the body
